Chapter 1. Using the Uniform Interface

HTTP is an application-level protocol that defines operations for transferring representations between clients and servers. In this protocol, methods such as GET , POST , PUT , and DELETE are operations on resources. This protocol eliminates the need for you to invent application-specific operations such as createOrder , getStatus , updateStatus , etc. How much you can benefit from the HTTP infrastructure largely depends on how well you can use HTTP as an application-level protocol. However, a number of techniques including SOAP and some Ajax web frameworks use HTTP as a protocol to transport messages. Such usage makes poor use of HTTP-level infrastructure. This chapter presents the following recipes to highlight various aspects of using HTTP as an application protocol:

1.1. How to Keep Interactions Visible

As an application protocol, HTTP is designed to keep interactions between clients and servers visible to libraries, servers, proxies, caches, and other tools. Visibility is a key characteristic of HTTP. Per Roy Fielding (see Appendix A for references), visibility is “ the ability of a component to monitor or mediate the interaction between two other components. ” When a protocol is visible, caches, proxies, firewalls, etc., can monitor and even participate in the protocol.

You want to know what visibility means and what you can do to keep HTTP requests and responses visible.

Once you identify and design resources, use GET to get a representation of a resource, PUT to update a resource, DELETE to delete a resource, and POST to perform a variety of potentially nonidempotent and unsafe operations. Add appropriate HTTP headers to describe requests and responses.

Features like the following depend entirely on keeping requests and responses visible:

Caching responses and automatically invalidating cached responses when resources are modified

Detecting concurrent writes and preventing resource changes when such operations are based on stale representations

Selecting a representation among alternatives available for a given resource

Ensuring that clients can repeat or retry certain HTTP requests

When a web service does not maintain visibility, such features will not work correctly. For instance, when the server’s usage of HTTP breaks optimistic concurrency, you may be forced to invent application-specific concurrency control mechanisms on your own.

Maintaining visibility lets you use existing HTTP software and infrastructure for features that you would otherwise have to build yourself.

HTTP achieves visibility by virtue of the following:

HTTP interactions are stateless. Any HTTP intermediary can infer the meaning of any given request and response without correlating them with past or future requests and responses.

HTTP uses a uniform interface consisting of OPTIONS , GET , HEAD , POST , PUT , DELETE , and TRACE methods. Each method in this interface operates on one and only one resource. The syntax and the meaning of each method do not change from application to application or from resource to resource. That is why HTTP is known as a uniform interface .

HTTP uses a MIME-like envelope format to encode representations. This format maintains a clear separation between headers and the body. Headers are visible, and except for the software that is creating the message and the software that is processing the message, every piece of software in between can treat the body as completely opaque.

Consider an HTTP request to update a resource:

Request line containing HTTP method, path to the resource, and HTTP version

Representation headers for the request

Representation body for the request

Response status line containing HTTP version, status code, and status message

Representation headers for the response

Representation body for the response

In this example, the request is an HTTP message. The first line in this message describes the protocol and the method used by the client. The next two lines are request headers. By simply looking at these three lines, any piece of software that understands HTTP can decipher not only the intent of the request but also how to parse the body of the message. The same is the case with the response. The first line in the response indicates the version of HTTP, the status code, and a message. The next two lines tell HTTP-aware software how to interpret the message.

For RESTful web services, your key goal must be to maintain visibility to the extent possible. Keeping visibility is simple. Use each HTTP method such that it has the same semantics as specified by HTTP, and add appropriate headers to describe requests and responses.

Another part of maintaining visibility is using appropriate status codes and messages so that proxies, caches, and clients can determine the outcome of a request. A status code is an integer, and the status message is text.

As we will discuss in Recipe 1.2 , there are cases where you may need to trade off visibility for other characteristics such as network efficiency, client convenience, and separation of concerns. When you make such trade-offs, carefully analyze the effect on features such as caching, idempotency, and safety.

1.2. When to Trade Visibility

This recipe describes some common situations where trading off visibility may be necessary.

You want to know common situations that may require you to keep requests and responses less visible to the protocol.

Whenever you have multiple resources that share data or whenever an operation modifies more than one resource, be prepared to trade visibility for better abstraction of information, loose coupling, network efficiency, resource granularity, or pure client convenience.

Visibility often competes with other architectural demands such as abstraction, loose coupling, efficiency, message granularity, etc. For example, think of a person resource and a related address resource. Any client can submit GET requests to obtain representations of these two resources. For the sake of client convenience, the server may include data from the address resource within the representation of the person resource as follows:

Let’s assume that the server allows clients to submit PUT requests to update these resources. When a client modifies one of these resources, the state of the related resource also changes. However, at the HTTP level, these are independent resources. Only the server knows that they are dependent. Such overlapping data is a common cause of reduced visibility.

One of the important consequences of reduced visibility is caching (see Chapter 9 ). Since these are two independent resources at the HTTP level, caches will have two copies of the address: one as an independent address representation and the other as part of the person representation. This can be inefficient. Also, invalidating one representation from the cache will not invalidate the other representation. This can leave stale representations in the cache.

In this particular example, you can eliminate the overlap between these resources by including a reference to the address from the person resource and avoid including address details. You can use links (see Chapter 5 ) to provide references to other resources.

Although providing a link may minimize overlaps, it will force clients to make additional requests.

In this example, the trade-off is between visibility and client convenience and, potentially, network efficiency. A client that always deals with person resources can make a single request to get information about the person as well as the address.

Here are some more situations where you may need to give up visibility for other benefits:

Servers may need to design special-purpose coarse-grained composite resources for the sake of client convenience (e.g., Recipe 2.4 ).

In order to abstract complex business operations (including transactions), servers may need to employ controller resources to make changes to other resources (e.g., Recipe 2.6 ). Such resources can hide the details used to implement business operations.

In cases where a client is performing several operations in quick succession, you may need to combine such operations into batches to reduce network latency (e.g., Recipes 11.10 and 11.13 ).

In each of these cases, if you focus only on visibility, you may be forced to design your web service to expose all data as independent resources with no overlaps. A web service designed in that manner may lead to fine-grained resources and poor separation of concerns between clients and servers. For an example, see Recipe 2.6 . Other scenarios such as copying or merging resources and making partial updates (see Chapter 11 ) may also require visibility trade-offs.

Provided you are aware of the consequences early during the design process, trading off visibility for other benefits is not necessarily bad.

1.3. How to Maintain Application State

Often when you read about REST, you come across the recommendation to “keep the application state on the client.” But what is “ application state ” and how can you keep that state on the client? This recipe describes how best to maintain state.

You want to know how to manage state in RESTful web services such that you do not need to rely on in-memory sessions on servers.

Encode application state into URIs, and include those URIs into representations via links (see Chapter 5 ). Let clients use these URIs to interact with resources. If the state is large or cannot be transported to clients for security or privacy reasons, store the application state in a durable storage (such as a database or a filesystem), and encode a reference to that state in URIs.

Consider a simplified auto insurance application involving two steps. In the first step, the client submits a request with driver and vehicle details, and the server returns a quote valid for a week. In the second step, the client submits a request to purchase insurance. In this example, the application state is the quote. The server needs to know the quote from the first step so that it can issue a policy based on that quote in the second request.

Application state is the state that the server needs to maintain between each request for each client. Keeping this state in clients does not mean serializing some session state into URIs or HTML forms, as web frameworks like ASP.NET and JavaServer Faces do.

Since HTTP is a stateless protocol, each request is independent of any previous request. However, interactive applications often require clients to follow a sequence of steps in a particular order. This forces servers to temporarily store each client’s current position in those sequences outside the protocol. The trick is to manage state such that you strike a balance between reliability, network performance, and scalability.

The best place to maintain application state is within links in representations of resources, as in the following example:

A link containing application state

In this example, the server stores the quote data in a data store and encodes its primary key in the URI. When the client makes a request to purchase insurance using this URI, the server can reinstate the application state using this key.

Choose a durable storage such as a database or a filesystem to store application state. Using a nondurable storage such as a cache or an in-memory session reduces the reliability of the web service as such state may not survive server restart. Such solutions may also reduce scalability of the server.

Alternatively, if the amount of data for the quote is small, the server can encode the state within the URI itself, as shown in the code below.

When you store application state in databases, use database replication so that all server instances have access to that state. If the application state is not permanent, you may also need to clean up the state at some point.

Since the client will need to send all that data back in every request, encoding the application state in links may reduce network performance. Yet it can improve scalability since the server does not need to store any data, and it may improve reliability since the server does not need to use replication. Depending on your specific use case and the amount of state, use a combination of these two approaches for managing application state, and strike a balance between network performance, scalability, and reliability.

When you store application state in links, make sure to add checks (such as signatures) to detect/prevent the tampering of state. See Recipe 12.5 for an example.

1.4. How to Implement Safe and Idempotent Methods on the Server

Safety and idempotency are guarantees that a server must provide to clients in its implementation for certain methods. This recipe discusses why these matter and how to implement safety and idempotency on the server.

You want to know what idempotency and safety mean, and what you can do to ensure that the server’s implementation of various HTTP methods maintain these two characteristics.

While implementing GET , OPTIONS , and HEAD methods, do not cause any side effects. When a client resubmits a GET , HEAD , OPTIONS , PUT , or DELETE request, ensure that the server provides the same response except under concurrent conditions (see Chapter 10 ).

Safety and idempotency are characteristics of HTTP methods for servers to implement. Table 1-1 shows which methods are safe and which are idempotent.

Implementing safe methods

In HTTP, safe methods are not expected to cause side effects. Clients can send requests with safe methods without worrying about causing unintended side effects. To provide this guarantee, implement safe methods as read-only operations.

Safety does not mean that the server must return the same response every time. It just means that the client can make a request knowing that it is not going to change the state of the resource. For instance, both the following requests may be safe:

In this example, the change in response between these two requests may have been triggered by some other client or some backend operation.

Implementing idempotent methods

Idempotency guarantees clients that repeating a request has the same effect as making a request just once. Idempotency matters most in the case of network or software failures. Clients can repeat such requests and expect the same outcome. For example, consider the case of a client updating the price of a product.

Now assume that because of a network failure, the client is unable to read the response. Since HTTP says that PUT is idempotent, the client can repeat the request.

For this approach to work, you must implement all methods except POST to be idempotent. In programming language terms, idempotent methods are similar to “setters.” For instance, calling the setPrice method in the following code more than once has the same effect as calling it just once:

Idempotency of DELETE

The DELETE method is idempotent. This implies that the server must return response code 200 ( OK ) even if the server deleted the resource in a previous request. But in practice, implementing DELETE as an idempotent operation requires the server to keep track of all deleted resources. Otherwise, it can return a 404 ( Not Found ).

Even when the server has a record of all the deleted resources, security policies may require the server to return a 404 ( Not Found ) response code for any resource that does not currently exist.

1.5. How to Treat Safe and Idempotent Methods in Clients

You want to know how to implement HTTP requests that are idempotent and/or safe.

Treat GET , OPTIONS , and HEAD as read-only operations, and send those requests whenever required.

In the case of network or software failures, resubmit GET , PUT , and DELETE requests to confirm, supplying If-Unmodified-Since and/or If-Match conditional headers (see Chapter 10 ).

Do not repeat POST requests, unless the client knows ahead of time (e.g., via server’s documentation) that its implementation of POST for any particular resource is idempotent.

Safe methods

Any client should be able to make GET , OPTIONS and HEAD requests as many times as necessary. If a server’s implementation causes unexpected side effects when processing these requests, it is fair to conclude that the server’s implementation of HTTP is incorrect.

Idempotent methods

As discussed in Recipe 1.4 , idempotency guarantees that the client can repeat a request when it is not certain the server successfully processed that request. In HTTP, all methods except POST are idempotent. In client implementations, whenever you encounter a software or a network failure for an idempotent method, you can implement logic to retry the request. Here is a pseudocode snippet:

In this example, the client implements logic to repeat the request only in the case of network failures, not when the server returned a 4xx or 5xx error. The client must continue to treat various HTTP-level errors as usual (see Recipe 3.14 ).

Since POST is not idempotent, do not apply the previous pattern for POST requests unless told by the server. Recipe 10.8 describes a way for servers to provide idempotency for POST requests.

1.6. When to Use GET

The infrastructure of the Web strongly relies on the idempotent and safe nature of GET . Clients count on being able to repeat GET requests without causing side effects. Caches depend on the ability to serve cached representations without contacting the origin server.

You want to know when and when not to use GET and the potential consequences of using GET inappropriately.

Use GET for safe and idempotent information retrieval.

Each method in HTTP has certain semantics. As discussed in Recipe 1.1 , the purpose of GET is to get a representation of a resource, PUT is to create or update a resource, DELETE is to delete a resource, and POST is either to create new resources or to make various other changes to resources.

Of all these methods, GET can take the least amount of misuse. This is because GET is both safe and idempotent.

Do not use GET for unsafe or nonidempotent operations. Doing so could cause permanent, unexpected, and undesirable changes to resources.

Most abuse of GET happens in the form of using this method for unsafe operations. Here are some examples:

For the server, all these operations are unsafe and nonidempotent. But for any HTTP-aware software, these operations are safe and idempotent. The consequences of this difference can be severe depending on the application. For example, a tool routinely performing health checks on a server by periodically submitting a GET request using the fourth URI shown previously will delete a note.

If you must use GET for such operations, take the following precautions:

Make the response noncacheable by adding a Cache-Control: no-cache header.

Ensure that any side effects are benign and do not alter business-critical data.

Implement the server such that those operations are repeatable (i.e., idempotent).

These steps may help reduce the impact of errors for certain but not all operations. The best course of action is to avoid abusing GET .

1.7. When to Use POST

This recipe summarizes various applications of POST .

You want to know the potential applications of the POST method.

Use POST for the following:

To create a new resource, using the resource as a factory as described in Recipe 1.8

To modify one or more resources via a controller resource as described in Recipe 2.6

To run queries with large inputs as described in Recipe 8.3

To perform any unsafe or nonidempotent operation when no other HTTP method seems appropriate

In HTTP, the semantics of method POST are the most generic. HTTP specifies that this method is applicable for the following. [ 1 ]

Annotation of existing resources;

Posting a message to a bulletin board, newsgroup, mailing list, or similar group of articles;

Providing a block of data, such as the result of submitting a form, to a data-handling process;

Extending a database through an append operation.

All such operations are unsafe and nonidempotent, and all HTTP-aware tools treat POST as such:

Caches do not cache responses of this method.

Crawlers and such tools do not automatically activate POST requests.

Most generic HTTP tools do not resubmit POST requests automatically.

Such a treatment gives great latitude for servers to use POST as a general-purpose method for a variety of operations, including tunneling. Consider the following:

This is an example of XML-RPC ( http://www.xmlrpc.com/ ) tunneling an operation via the POST method. Another popular example is SOAP with HTTP:

Both these approaches misuse the method POST . For this example, the DELETE method is more appropriate:

When there is no such direct mapping between the application’s operations and HTTP, using POST has less severe consequences than overloading other HTTP methods.

In addition, the following situations force you to use POST even when GET is the right method to use:

HTML clients like browsers use the URI of the page as the Referer header while making requests to fetch any linked resources. This may leak any sensitive information contained in the URI to external servers.

In such cases, if using Transport Layer Security (TLS, a successor to SSL) or if the encryption of any sensitive information in the URI is not possible, consider using POST to serve HTML documents.

As discussed in Recipe 8.3 , POST may be the only option when queries from clients contain too many parameters.

Even in these conditions, use POST only as the last resort.

1.8. How to Create Resources Using POST

One of the applications of POST is to create new resources. The protocol is similar to using the “ factory method pattern ” for creating new objects.

You want to know how to create a new resource, what to include in the request, and what to include in the response.

Identify an existing resource as a factory for creating new resources. It is common practice to use a collection resource (see Recipe 2.3 ) as a factory, although you may use any resource.

Let the client submit a POST request with a representation of the resource to be created to the factory resource. Optionally support the Slug header to let clients suggest a name for the server to use as part of the URI of the resource to be created.

After creating the resource, return response code 201 ( Created ) and a Location header containing the URI of the newly created resource.

If the response body includes a complete representation of the newly created resource, include a Content-Location header containing the URI of the newly created resource.

Consider the case of creating an address resource for a user. You can take the user resource as a factory to create a new address:

User resource acting as a factory to create a home address resource

A suggestion for naming the URI of the new resource

URI of the newly created resource

URI of representation in the response

In this example, the request contains data to create a new resource, and a Slug header with a suggestion for the URI of the new resource. Note that the Slug header is specified by AtomPub (RFC 5023). This header is just a suggestion from the client. The server need not honor it. See Chapter 6 to learn about AtomPub.

The status code of the response 201 indicates that the server created a new resource and assigned the URI http://www.example.org/user/smith/address/home_address to it, as indicated by the Location response header. The Content-Location header informs the client that the body of the representation can also be accessed via the URI value of this header.

Along with the Content-Location header, you can also include the Last-Modified and ETag headers of the newly created resource. See Chapter 10 to learn more about these headers.

1.9. When to Use PUT to Create New Resources

You can use either HTTP POST or HTTP PUT to create new resources. This recipe discusses when to use PUT to create new resources.

You want to know when to use PUT to create new resources.

Use PUT to create new resources only when clients can decide URIs of resources. Otherwise, use POST .

Here is an example of a client using PUT to create a new resource:

Client using PUT to create a new resource

Use PUT to create new resources only when the client can control part of the URI. For instance, a storage server may allocate a root URI for each client and let clients create new resources using that root URI as a root directory on a filesystem. Otherwise, use POST .

When using POST to create new resources, the server decides the URI for the newly created resource. It can control its URI naming policies along with any network security-level configurations. You can still let servers use information in the representation (such as the Slug header) while generating URIs for new resources.

When you support PUT to create new resources, clients must be able to assign URIs for resources. When using this method to create new resources, take the following into consideration:

To let clients assign URIs, the server needs to explain to clients how URIs on the server are organized, what kind of URIs are valid, and what kind are not.

You also need to consider any security and filtering rules set up on servers based on URI patterns and may want to restrict clients to use a narrow range of URIs while creating new URIs.

In general, any resource that can be created via PUT can equivalently be created by using POST with a factory resource. Using a factory resource gives the server more control without explaining its URI naming rules. An exception is the case of servers providing a filesystem-like interface for clients to manage documents. WebDAV (see Recipe 11.4 ) is an example.

1.10. How to Use POST for Asynchronous Tasks

HTTP is a synchronous and stateless protocol. When a client submits a request to a server, the client expects an answer, whether the answer is a success or a failure. But this does not mean that the server must finish processing the request before returning a response. For example, in a banking application, when you initiate an account transfer, the transfer may not happen until the next business day, and the client may be required to check for the status later. This recipe discusses how to use this method to process requests asynchronously.

You want to know how to implement POST requests that take too long to complete.

On receiving a POST request, create a new resource, and return status code 202 ( Accepted ) with a representation of the new resource. The purpose of this resource is to let a client track the status of the asynchronous task. Design this resource such that its representation includes the current status of the request and related information such as a time estimate.

When the client submits a GET request to the task resource, do one of the following depending on the current status of the request:

Return response code 200 ( OK ) and a representation of the task resource with the current status.

Return response code 303 ( See Other ) and a Location header containing a URI of a resource that shows the outcome of the task.

Return response code 200 ( OK ) with a representation of the task resource informing that the resource creation has failed. Clients will need to read the body of the representation to find the reason for failure.

Consider an image-processing web service offering services such as file conversions, optical character recognition, image cleanup, etc. To use this service, clients upload raw images. Depending on the nature and size of images uploaded and the current server load, the server may take from a few seconds up to several hours to process each image. Upon completion, client applications can view/download processed images.

Let’s start with the client submitting a POST request to initiate a new image-processing task:

In this example, the client uses a multipart message, with the first part containing an XML document describing the kind of image-processing operations the server needs to perform and the second part containing the image to be processed.

Upon ensuring that the contents are valid and that the given image-processing request can be honored, let the server create a new task resource:

Response code indicating that the server accepted the request for processing

A hint to check for the status at a later time

The client can subsequently send a GET request to this task resource. If the server is still processing the task, it can return the following response:

See Recipe 3.9 to learn the rationale behind the choice of the date-time value for the ping-after element.

After the server successfully completes image processing, it can redirect the client to the result. In this example, the result is a new image resource:

See the target resource for the result.

The response code 303 merely states that the result exists at the URI indicated in the Location header. It does not mean that the resource at the request URI (e.g., http://www.example.org/images/task/1 ) has moved to a new location.

This representation informs the client that it needs to refer to http://www.example.org/images/1 for the result. If, on the other hand, the server fails to complete the task, it can return the following:

1.11. How to Use DELETE for Asynchronous Deletion

This recipe outlines an approach for using DELETE for asynchronous tasks. This recipe is appropriate when resource deletion takes a significant amount of time for cleanup and archival tasks in the backend.

You want to know how to implement DELETE requests that take too long to complete.

On receiving a DELETE request, create a new resource, and return 202 ( Accepted ) with the response containing a representation of this resource. Let the client use this resource to track the status. When the client submits a GET request to the task resource, return response code 200 ( OK ) with a representation showing the current status of the task.

Supporting asynchronous resource deletion is even simpler than creating or updating resources. The following sequence of steps illustrates an implementation of this recipe:

To begin, a client submits a request to delete a resource.

The server creates a new resource and returns a representation indicating the status of the task.

The client can query the URI http://www.example.org/task/1 to learn the status of the request.

You can use the same approach for asynchronously updating a resource via the PUT method.

1.12. When to Use Custom HTTP Methods

There were several attempts to extend HTTP with new methods. The most prominent attempt was WebDAV ( http://www.webdav.org ). WebDAV defines several HTTP methods, such as PROPFIND , PROPPATCH , MOVE , LOCK , UNLOCK , etc., for distributed authoring and versioning of documents (see Recipe 11.4 ). Other examples include PATCH ( Recipe 11.9 ) for partial updates and MERGE ( http://msdn.microsoft.com/en-us/library/cc668771.aspx ) for merging resources.

You want to know the consequences of using custom HTTP methods.

Avoid using nonstandard custom HTTP methods. When you introduce new methods, you cannot rely on off-the-shelf software that only knows about the standard HTTP methods.

Instead, design a controller (see Recipe 2.6 ) resource that can abstract such operations, and use HTTP method POST .

The most important benefit of extending methods is that they let servers define clear semantics for those methods and keep the interface uniform. But unless widely supported, extension methods reduce interoperability.

For example, WebDAV defines the semantics of MOVE as a “logical equivalent of a copy (COPY), followed by consistency maintenance processing, followed by a delete of the source, where all three actions are performed atomically.” Any client can submit an OPTIONS request to determine whether a WebDAV resource implements MOVE . When necessary, if a resource supports this method, the client can submit a MOVE request to move a resource from one location to another.

It is certainly possible to follow WebDAV’s approach and design a new method, say, CLONE , to create a clone of an existing resource:

Clients will then be able to discover support for this method and submit a CLONE request.

In reality, proxies, caches, and HTTP libraries will treat such methods as nonidempotent, unsafe, and noncacheable. In other words, they apply the same rules to such extension methods as POST , which is nonidempotent, unsafe, and most often noncacheable. This is because idempotency and safety are guarantees that the server must explicitly provide. For unknown custom methods, proxies, caches, and HTTP libraries cannot assume that the server provides such guarantees. Therefore, for most HTTP-aware software and tools, custom HTTP methods are synonymous with POST .

Moreover, not all HTTP software (including firewalls) may support arbitrary extension methods. Therefore, use custom methods only when wide interoperability is not a concern.

Prefer POST over custom HTTP methods. Not every HTTP software lets you use custom HTTP methods. Using POST is a safer option.

1.13. When and How to Use Custom HTTP Headers

It is not uncommon to find HTTP servers using custom headers. Some well-known custom headers include X-Powered-By , X-Cache , X-Pingback , X-Forwarded-For , and X-HTTP-Method-Override . HTTP does not prohibit such extension headers, but depending on what clients and servers use custom headers for, custom headers may impede interoperability. This recipe discusses when and how to use custom HTTP headers.

You want to know the common conventions and best practices for using custom HTTP headers.

Use custom headers for informational purposes. Implement clients and servers such that they do not fail when they do not find expected custom headers.

Avoid using custom HTTP headers to change the behavior of HTTP methods. Limit any behavior-changing headers to the method POST .

If the information you are conveying through a custom HTTP header is important for the correct interpretation of the request or response, include that information in the body of the request or response or the URI used for the request. Avoid custom headers for such usages.

Most websites using the WordPress blogging platform ( http://wordpress.org ) include the following HTTP headers in responses:

Such headers are not part of HTTP. The first header is generated by the PHP runtime that WordPress is built on. It indicates that the server is using a particular version of PHP on Ubuntu. The X-Pingback header contains a URI that clients can use to notify WordPress when a reference is made on some other server to the resource. Similarly, HTTP caching proxy Squid uses X-Cache headers to inform clients whether the representation in the response is being served from the cache.

Such usages are informational. Clients receiving those headers are free to ignore them without loss of functionality. Another commonly used informational header is X-Forwarded-By .

The purpose of this header is to convey the source of the request to the server. Some proxies and caches add this header to report the source of the request to the server. In this example, the server received a request from 192.168.123.10 via 192.168.123.14 . If all proxies and caches that the request is served through augment this header, then the server can determine the IP address of the client.

Although names of some custom headers start with X- , there is no established convention for naming these headers. When you introduce custom headers, use a convention such as X-{company-name}-{header-name} .

The following custom HTTP headers are not informational and may be required for the correct processing of requests or responses:

Avoid such usages. They weaken the use of URIs as resource identifiers and HTTP methods as operations.

Another commonly used custom header is X-HTTP-Method-Override . This header was initially used by Google as part of the Google Data Protocol ( http://code.google.com/apis/gdata/docs/2.0/basics.html ). Here is an example:

In this case, the client uses X-HTTP-Method-Override with a value of PUT to override the behavior of the method used for the request, which is POST . The rationale for this extension was to tunnel the method PUT over POST so that any firewalls configured to block PUT will permit the request.

Instead of using X-HTTP-Method-Override to override POST , use a distinct resource to process the same request using POST without that header. Any HTTP intermediary between the client and the server may omit custom headers.

Jersey client: com.sun.jersey.api.client.uniforminterfaceexception.

As I mentioned in a post a couple of weeks ago we’ve been doing some which involved calling the neo4j server’s HA URI to determine whether a machine was slave or master.

We started off with the following code using jersey-client :

which works fine when the server is actually a slave:

but blows up in style if the server is the master:

We return a 404 status code from that URI if you’re not a slave because it simplifies things for upstream load balancers but I thought Jersey would just return the body of the response rather than throwing an exception.

A quick browse of the Jersey code showed a way around this:

WebResource#handle gets called by WebResource#get and if we pass ClientResponse.class to it instead of String.class we can get around this because the code returns without checking the status of the response.

Our code needs to read like this:

And if we run it, this time we get the expected result:

REST API Tutorial

REST Architectural Constraints

REST defines 6 architectural constraints which make any web service – a truly RESTful API i.e. Uniform interface, Client–server, Stateless, Cacheable, Layered system, Code on demand (optional).

Written by: Lokesh Gupta

Last Updated: November 6, 2023

REST stands for Re presentational S tate T ransfer, a term coined by Roy Fielding in 2000. It is an architecture style for designing loosely coupled applications over the network, that is often used in the development of web services.

REST does not enforce any rule regarding how it should be implemented at the lower level, it just puts high-level design guidelines and leaves us to think of our own implementation.

In my last employment, I designed RESTful APIs for a major telecom company for two good years. In this post, I will be sharing my thoughts apart from standard design practices. You may not agree with me on a few points, and that’s perfectly OK. I will be happy to discuss anything with you with an open mind.

Let’s start with standard design-specific stuff to clarify what ‘Roy Fielding’ wants us to build. Then we will discuss my thoughts, which will be more towards finer points while you design your RESTful APIs.

Architectural Constraints

REST defines 6 architectural constraints that make any web service – a truly RESTful API.

• Uniform interface
• Client-server
• Layered system
• Code on demand (optional)

1. Uniform interface

As the constraint name itself applies, you MUST decide APIs interface for resources inside the system which are exposed to API consumers and follow religiously. A resource in the system should have only one logical URI, and that should provide a way to fetch related or additional data. It’s always better to synonymize a resource with a web page .

Any single resource should not be too large and contain each and everything in its representation. Whenever relevant, a resource should contain links (HATEOAS) pointing to relative URIs to fetch related information.

Also, the resource representations across the system should follow specific guidelines such as naming conventions, link formats, or data format (XML or/and JSON).

All resources should be accessible through a common approach such as HTTP GET and similarly modified using a consistent approach.

Once a developer becomes familiar with one of your APIs, he should be able to follow a similar approach for other APIs.

2. Client-server

This constraint essentially means that client applications and server applications MUST be able to evolve separately without any dependency on each other. A client should know only resource URIs, and that’s all. Today, this is standard practice in web development, so nothing fancy is required from your side. Keep it simple.

Servers and clients may also be replaced and developed independently, as long as the interface between them is not altered.

3. Stateless

Roy fielding got inspiration from HTTP, so it reflected in this constraint. Make all client-server interactions stateless. The server will not store anything about the latest HTTP request the client made. It will treat every request as new. No session, no history.

If the client application needs to be a stateful application for the end-user, where the user logs in once and does other authorized operations after that, then each request from the client should contain all the information necessary to service the request – including authentication and authorization details.

No client context shall be stored on the server between requests. The client is responsible for managing the state of the application.

4. Cacheable

In today’s world, the caching of data and responses is of utmost importance wherever they are applicable/possible. The webpage you are reading here is also a cached version of the HTML page. Caching brings performance improvement for the client side and better scope for scalability for a server because the load has been reduced.

In REST, caching shall be applied to resources when applicable, and then these resources MUST declare themselves cacheable. Caching can be implemented on the server or client side.

Well-managed caching partially or completely eliminates some client-server interactions, further improving scalability and performance.

5. Layered system

REST allows you to use a layered system architecture where you deploy the APIs on server A, and store data on server B and authenticate requests in Server C, for example. A client cannot ordinarily tell whether it is connected directly to the end server or an intermediary along the way.

6. Code on demand (optional)

Well, this constraint is optional. Most of the time, you will be sending the static representations of resources in the form of XML or JSON. But when you need to, you are free to return executable code to support a part of your application, e.g., clients may call your API to get a UI widget rendering code. It is permitted.

All the above constraints help you build a truly RESTful API, and you should follow them. Still, at times, you may find yourself violating one or two constraints. Do not worry; you are still making a RESTful API – but not “truly RESTful.”

Notice that all the above constraints are most closely related to WWW (the web). Using RESTful APIs, you can do the same thing with your web services that you do to web pages.

Happy Learning !!

This 52-Foot Cruiser Delivers Superyacht Amenities in a Compact Package

• Share This Article

Absolute Yachts ’ most recent model is the 52 Fly, which rolled out at the 2023 Miami International Boat Show. From the first step aboard, it was clear the Italian builder had sweated not only the details, but also pushed the genre ahead of its competition.

The hull’s glazing, resembling a short, tanto-bladed knife and a vertical bow up front, also added to the contemporary design. Undulating LED lighting inlays in the cockpit overhang imparted a cool, sophisticated look to the space. At the same time, a starboard-side docking station spoke to this boat’s bona fides as a serious cruising machine.

The salon also had design touches that one might not expect to find on a 52-ft. semi-custom build. The aft galley had a four-burner Bosch cooktop and a six-foot-tall, stacked refrigerator and freezer that is useful for longer trips. The drawers all had chic leather tabs as handles, extending a beach-like, elegant vibe to the space.

The starboard-side helm was another place onboard that feels just a little bit different than the standard offerings in this size and class.

Twin Garmin screens were angled off in a small arc, as opposed to facing straight back, which gave them a slightly futuristic feel. Tightly stitched helix patterns in the seat-backs of the helm chairs pointed towards a high level of fit and finish.

A sturdy door next to the helm led to the side deck. Perhaps most important for the helmsperson, the Volvo Penta joystick control was maneuverable while standing on that side deck. The joystick and cockpit control station should make docking this boat easier than a conventional setup.

One of the other significant layouts was the flybridge. Absolute managed to make it look stylish and large, without appearing top heavy. The design included a large forward lounge surrounding the helm station, with back-to-front seats to port, and an L-shaped lounge extending back to the transom, with a center dining table. The side island with fridge can also double as a serving station. The overhead hardtop had an opening center window, and stereo speakers were embedded into the bridge.

Our final impression after a tour aboard: The Absolute 52 Fly was more than the sum of its parts. The boat was full-featured without looking crowded, but also highly functional. This 52-footer was clearly ready for a weekend cruise or extended voyage. The Italian builder proved that a well-conceived design makes for a well-rounded boat.

Absolute Yachts Launches Generation 2022 Models With New '60 Fly'

By: Scott Way

Italian boatbuilders Absolute Yachts is laying the groundwork for their future with the launch of a new 'Generation 2022' lineup. Among the 2022 models will be the all-new 60 Fly, which the company has dubbed "The Absolute Prisma."

According to the press release , the new 60 Fly was designed to "redefine the range with new ground-breaking design elements never seen on a Flybridge boat of these dimensions." Among the most notable highlights are a raised owner's quarters at the bow and a huge aft cockpit terrace.

The bow master cabin features a rare full beam design that's raised from the lower deck. With an LOA of 61'3" (18.6m) and a beam of 16'2" (4.94m) the 60 Fly devotes significant attention to maximizing interior space. Despite the cabin orientation, it still carries high ceilings and includes a walk-in wardrobe, vanity with a sea view, and large side windows to let ambient light and an impressive view reach inside.

Glazed balustrades create expansive views from both the fly and the cockpit to coincide with the ample window placements. Both the cockpit and the fly can be custom furnished to the owner's preference. The aft cockpit includes two staircases to the wide stern platform which include a large terrace just above the water. The terrace also provides an entrance to the crew cabin via a pantograph door concealed in the transom.

The Fly boasts a generously sized open-air salon with panoramic views and smartly placed appointments. Notable features include an al-fresco galley and dining area, ample lounge space, and an impressive helm station with forward-thinking tech. The flybridge also includes double piloting seats and a wideset windscreen with minimized support pillars for an unobstructed view, as well as a sofa and sundeck next to the helm for extra company.

As for the helm stations, both the flybridge and main deck include double piloting seats and a wideset windscreen with minimized support pillars for an unobstructed view. The hardtop also includes optional solar panels as a secondary power source and to minimize generator usage and emissions. Engine power comes from Volvo Penta 2xD11 IPS950 diesels with 615 US gallon (2300 litre) capacity. A third mooring station is available at the stern which can be integrated on the starboard side. The station can be equipped with a bow thruster, joystick, and engine ignition panel.

Inside the boat has three staterooms with full toilets and separated showers. Two staterooms carry king-size beds while a third cabin carries two twin-size accommodations. The crew cabin includes two bunks. The master cabin also includes a sofa, vanity console, full closet, and ample storage space.

The new 60 Fly is expected to be unveiled at the Cannes Yachting Festival in September 2021 along with another new model in the Generation 2022 lineup, the Absolute 48 Coupe.

You can get the first look at the new 60 Fly in the video below:

Absolute Yachts, when the made in Italy model is a success

In its just 18 years of existence, the Absolute Yachts shipyard has grown to be one of the most interesting players on the global nautical scene 

by Francesco Michienzi

Absolute Yachts is one of the few shipyards in the world that can boast a financial statement, which displays a nice and round zero under the item “debts”. This is where you need to start if you want to understand the continuous ascent of this all-Italian company, which has made financial rigour into its strength.

The double A bank rating, the 63 million Euro turnover, an Ebitda of 19.5 per cent, and 19 million in liquidity, allow it to face international markets with the necessary serenity . The economic and financial aspect, however, is only the premise of an entrepreneurial philosophy based on concreteness and on the idea of a cohesive society. The people who work in the shipyard are part of a large family where each member is called upon to make his or her contribution and to be fully aware of the importance of the role they play. Workers, craftsmen, employees, designers, and managers all move in harmony to obtain the very best.

Marcello Bè and Sergio Maggi founded Absolute in 2002, strong with their long experience in the industry and with their futuristic vision of how to do business in the nautical industry. The great turn of events came with a series of new entries into the company: Patrizia Gobbi , Paola Carini , Giuseppe Bertocci and Angelo Gobbi , who took on the presidency in 2007.

The partners all work in the company and each one deals with a specific aspect of the business, without saving either physical nor intellectual energy. The results are immediacy and sharing on every level, a clear awareness of the goals and methods established to obtain them, and the satisfaction of working in a cohesive team. In an environment like this, it is only natural to find material and immaterial elements of both individual and collective gratification .

Over the past ten years, the company has acquired international fame, wit h about 90 vessels produced per year, divided into four lines ranging from 40 to 73 feet , Flybridge, Sport Line, Sport Yacht, and Navetta . Thanks to 40 dealers, the brand is now distributed in 20 countries all over the world. We had the pleasure of visiting the plants exactly ten years after the construction of the new shipyards. Already then, it looked like the offspring of an innovative vision, thanks to certain choices that clearly showed an industrial development aimed at quality – both on the site and in terms of the people working on it.

The general feeling we had was a mix of amazement and admiration. Boats are products that require a great amount of manual work, which needs to be carried out by expert hands, and the industrial process must take this into consideration. In fact, to reach ideal results, both from the point of view of quality and from the point of view of financial competitiveness, everything needs to be strongly based on a valid project.

In Podenzano we had the pleasant feeling of standing in an authentic industry, where everything was thought through down to the smallest detail to obtain the very best result from every action. Over the past ten years, the automated vertical warehouse and ventilation systems in the lamination department have been doubled.

The facilities have moreover been equipped with an automatic resin feeding system and a new CNC work centre for the carpentry department and for the storage and automatic movement of plywood. The construction of a new pool to test all the on-board equipment is planned for 2019. Absolute Yachts independently manages every single stage of their boats’ life cycle : concept, design, engineering, modelling, creation of moulds and setup of the production, lamination, and structural assembly, installation and assembly of equipment and furniture, tests, delivery logistics, and final setup of the boat. The covered surface of the plant dedicated to production is 30 thousand square metres within an overall area of 58 thousand.

Angelo Gobbi is particularly proud of the flattering results obtained in recent years:

«We want people to understand who we are and where we are going, the nautical world has changed. When sacrifices were required, our company actually implemented what no other entrepreneur in the nautical business even envisioned: we invested even more financial resources in order to oil and fix the machine anew» .

Even during the toughest moments of the global financial crisis, when the consumption of luxury goods experienced significant reductions, the company stood strong: «We adapted, we changed our models and diversified in new countries where we could distribute our boats. In 2013, there was a significant recovery in our turnover, we conquered new markets and allowed the turnover to keep growing constantly. Today, 240 people work in our plant and offices producing about 90 vessels per year».

Absolute Yachts Debuts 60 Fly

• By Victor Tan
• Updated: September 16, 2021

The Absolute Yachts 60 Fly adds to the Italian builder’s eight-model flybridge series, which ranges from 47 feet to 72 feet length overall. The 60 Fly carries a fair bit of beam forward, enhancing interior volume and allowing space for a full-beam master stateroom at the bow. In addition to a walk-in closet, this space has a vanity and hullside windows offering sea views. A VIP stateroom with an en suite head is amidships and to starboard. A third guest stateroom is to port with twin berths. The crew cabin is aft with twin berths.

Unobstructed ocean views are the core of the 60 Fly’s design, with cut-down bulwarks amidships and nearly 360 degrees of glass in the vessel’s superstructure. The salon has a U-shaped settee to port, while aft and to starboard is a U-shaped dining area. Across from the dining area, to port, is an L-shaped galley with direct access to the cockpit via sliding doors. With the sliding doors open, the salon and cockpit are an end-to-end entertainment space.

Owners can personalize the cockpit with modular furniture. One layout has a dining table with six chairs protected by the flybridge overhang. Prefer lounge-style or loose chairs? They’re options.

There is also a foredeck bench seat against the house, as well as an adjustable backrest on the seating forward of it, using part of the sun pad to create a second bench seat. Or slide the backrest to optimize the sun-pad space.

The 60 Fly has upper and lower helm stations, each equipped with dual helm seats and Garmin electronics.

Power is twin Volvo Penta D11 IPS950s. Projected performance data was not available at press time. The 60 Fly’s hardtop can be equipped with solar panels to run ship’s systems in silence.

Look for the Absolute Yachts 60 Fly to debut this fall.

ABSOLUTE YACHTS: Four exceptional yachts presented in a prestigious setting

Absolute Yachts returns to Germany for boot Düsseldorf, presenting four models from the Absolute fleet; 48 Coupé, 52 Fly, Navetta 52 and Navetta 58. With estimated attendance at about 237,000 visitors and over 1,500 exhibitors, boot is the world’s largest yacht and watersports trade show, held at the Messe Düsseldorf trade fair district.

deneme bonusu veren siteler 2024

The 48 Coupé – “The Absolute horizon” – embodies the latest and sportiest trends of luxury yachting. It combines the impeccable comfort with a dynamic profile, distinctive design, and a constant focus on the nautical experience. This is guaranteed by the excellent visibility provided by the open bulwarks and the glazed balustrades astern. Inside, panoramic views are assured by the exceptionally large areas of glazing both in the salon, and in the three staterooms below decks, with their large hull windows ensuring excellent natural lighting. The level of comfort in all the interior spaces is at Absolute’s characteristically high standards of luxury. Sustainability, always a key factor in the brand’s design outlook, can be seen in the solar panels on the roof and in the electrically-opening windows, which make it possible to activate natural air circulation, reducing energy usage for air conditioning.

ABSOLUTE 52 FLY

The Absolute 52 Fly, presented in 2023, is the newest yacht in the Flybridge range. This yacht has been named the “Absolute direction”, because it has introduced an entirely new direction in luxury yachts, including a cutting-edge design with features that are normally found only on much larger yachts. In fact, alongside the characteristics that hallmark all Absolute yachts, such as ample headroom, floors with a minimum of steps, and the extensive use of sliding doors, the truly astonishing feat in the 52 Fly is the massive space throughout. The salon is roomy and beautifully detailed, served by a superbly-equipped galley that even has a large pantry and a full-height fridge-freezer. The full-beam owner stateroom is located in the bow location to ensure privacy and quiet, and it has a fine marble bathroom with extensive storage units. The VIP stateroom midships can be considered as a second master stateroom, with generous space and impeccable finish. The third guest cabin has twin berths, with good headroom and an electrically-operated system that enables its transformation into a double berth. In addition, there is a multi-function crew cabin aft. Outside, there are multiple deck areas that provide space an openness including a generously sized cockpit terrace that is distinctive thanks to its open bulwarks. Above, the superbly designed flybridge is conveniently equipped with free-standing furniture, a wet bar, and galley to enhance the experience for you and your guests. Finally, the bow area is comfortably outfitted with a three-person sunlounger, teak table, and settes for the perfect ambiance.

Navetta 52 – known as the “Absolute Leader” – was designed to ensure high levels of cruising comfort in all conditions. The side decks are protected above by a cantilevered superstructure and at the side by sturdy bulwarks, and the cockpit terrace is also entirely covered by the flybridge. The same all-weather appeal can be seen on the foredeck, where the settee is shaded behind the loungers for soaking up the sun. The flybridge is exceptionally large, a privileged location for around-the-clock enjoyment, with a dinette, an outdoor galley, and an aft terrace area with moveable seating for maximum flexibility. The flybridge helm is accompanied by sofas for sailing with friends. Inside the main salon, the vast windows are accompanied by Absolute’s skill in sophisticated, minimalist interior design. The galley is positioned so that it can serve both the salon and the cockpit terrace, and if required it can be separated by electrically-operated vertical glass screens. The main helm station is modern and ergonomic, with a door opening onto the side deck so that the captain can use the joystick when outside during mooring.

Navetta 58, known as the “Absolute Appeal”, is a yacht very different from the traditional design standards, making it a true leader in its category. Its plumb bow and distinctive architecture ensure generous dimensions, as can be seen on the flybridge. This space has an aft area for relaxation, a central area with dinette and grill, and a flybridge helm station forward at the bow that includes additional seating comprising of two L-shaped settees. On the main deck, the cockpit terrace is furnished with a sofa and dining table, and it provides access to the salon, where the galley – whose facilities include a large worktop, a full-sized fridge, a four-burner hob, a sink and a dishwasher – is located just aft of the principal helm station. Below decks, accommodations consist of a master stateroom midships and a VIP suite in the bows, both with pillarless windows, spacious storage, en-suite bathrooms, and sophisticated furnishings. A third guest cabin has twin beds, seamlessly transformable to a double berth.

The Navetta 64 is clearly a sibling in the Absolute model line thanks to the unique exterior lines.

Abord the Navetta 64, the exterior lines are outlined by the opening of the side gunwale in the aft cockpit and the unparalleled wide windows in the bow. There is a vivid richness of textures and low reliefs that act as protagonists in the harmonic contrasts of shapes, lights, shadows, and colors.

Aboard the new Navetta 64 the Flybridge is surprisingly wide, larger than any other Navetta model, and even many other competitive yachts. The flybridge space mirrors the versatility of the salon, improving your experience on board through its complete and outstanding level of comfort.

Guests will enjoy the convenience of the wetbar near the salon, a gorgeous, well-equipped galley, a sofa with large teak table, and a wide foredeck lounge with furnishings customized to your tastes. Also featured is the optional perimeter guide, a transparent cover that allows for closing off of the flybridge from inclement weather without sacrificing the panoramic views.

The ergonomic helm station has cutting-edge technology needed for full control of the yacht from navigation to steering. Two couches just aft of the inside helm station allows for the captain to feel as if they’re surrounded by friends while driving, in total safety.

Aboard the Absolute Navetta 64, every detail is designed to assure maximum comfort and functionality. Just like at home, but surrounded by the sea.

All spaces on board are designed to offer maximum enjoyment with beautiful natural light, thanks to the unprecedented large windows that also offer picture-sized views. From the salon to every cabin, the furnishings and appointments are refined to make you feel at ease, without compromise.

On the main deck, the salon is a jewel embroidered with a breath-taking view, thanks to the surrounding windows with reduced-size pillars.

Below deck, the full-beam master cabin is placed in the bow allowing for extra space, as well as a full-beam bathroom.

Your guests will relax in luxury whether in the extraordinary VIP suite or the double-sized third cabin featuring two single beds. Every stateroom on the Navetta 64 features its own en suite head.

Aboard the Absolute Navetta 64, the exciting new Beach Club is both a luxurious fourth double-cabin and an exclusive sea-side terrace.

In the Beach Club version, the transom can be turned from a large storage area into an actual VIP cabin right at the water’s surface.  The certified watertight access door is fully tinted and slightly curved for an incredible visual effect.

Beach Club by day and double cabin with an en-suite head by night. This transformation is made possible by moving the double crew cabin, now directly accessible from the second starboard side door.

REST stands for REpresentational State Transfer and API stands for Application Program Interface. REST is a software architectural style that defines the set of rules to be used for creating web services. Web services which follow the REST architectural style are known as RESTful web services. It allows requesting systems to access and manipulate web resources by using a uniform and predefined set of rules. Interaction in REST based systems happen through Internet’s Hypertext Transfer Protocol (HTTP). 

A Restful system consists of a:

• client who requests for the resources.
• server who has the resources.

It is important to create REST API according to industry standards which results in ease of development and increase client adoption. 

Architectural Constraints of RESTful API: There are six architectural constraints which makes any web service are listed below:

• Uniform Interface
• Client-Server
• Layered System
• Code on Demand

The only optional constraint of REST architecture is code on demand. If a service violates any other constraint, it cannot strictly be referred to as RESTful. 

Uniform Interface: It is a key constraint that differentiate between a REST API and Non-REST API. It suggests that there should be an uniform way of interacting with a given server irrespective of device or type of application (website, mobile app). 

There are four guidelines principle of Uniform Interface are:

• Resource-Based: Individual resources are identified in requests. For example: API/users.
• Manipulation of Resources Through Representations: Client has representation of resource and it contains enough information to modify or delete the resource on the server, provided it has permission to do so. Example: Usually user get a user id when user request for a list of users and then use that id to delete or modify that particular user.
• Self-descriptive Messages: Each message includes enough information to describe how to process the message so that server can easily analyses the request.
• Hypermedia as the Engine of Application State (HATEOAS): It need to include links for each response so that client can discover other resources easily.

Stateless: It means that the necessary state to handle the request is contained within the request itself and server would not store anything related to the session. In REST, the client must include all information for the server to fulfill the request whether as a part of query params, headers or URI. Statelessness enables greater availability since the server does not have to maintain, update or communicate that session state. There is a drawback when the client need to send too much data to the server so it reduces the scope of network optimization and requires more bandwidth.

Cacheable: Every response should include whether the response is cacheable or not and for how much duration responses can be cached at the client side. Client will return the data from its cache for any subsequent request and there would be no need to send the request again to the server. A well-managed caching partially or completely eliminates some client–server interactions, further improving availability and performance. But sometime there are chances that user may receive stale data. 

Client-Server: REST application should have a client-server architecture. A Client is someone who is requesting resources and are not concerned with data storage, which remains internal to each server, and server is someone who holds the resources and are not concerned with the user interface or user state. They can evolve independently. Client doesn’t need to know anything about business logic and server doesn’t need to know anything about frontend UI. 

Layered system: An application architecture needs to be composed of multiple layers. Each layer doesn’t know any thing about any layer other than that of immediate layer and there can be lot of intermediate servers between client and the end server. Intermediary servers may improve system availability by enabling load-balancing and by providing shared caches. 

Code on demand: It is an optional feature. According to this, servers can also provide executable code to the client. The examples of code on demand may include the compiled components such as Java Servlets and Server-Side Scripts such as JavaScript. 

Rules of REST API: There are certain rules which should be kept in mind while creating REST API endpoints.

• REST is based on the resource or noun instead of action or verb based. It means that a URI of a REST API should always end with a noun. Example: /api/users is a good example, but /api?type=users is a bad example of creating a REST API.
• HTTP verbs are used to identify the action. Some of the HTTP verbs are – GET, PUT, POST, DELETE, GET, PATCH.
• A web application should be organized into resources like users and then uses HTTP verbs like – GET, PUT, POST, DELETE to modify those resources. And as a developer it should be clear that what needs to be done just by looking at the endpoint and HTTP method used.
• Always use plurals in URL to keep an API URI consistent throughout the application.
• Send a proper HTTP code to indicate a success or error status.

Note : You can easily use GET and POST but in order to use PUT and DELETE you will need to install method override. You can do this by following below code :

This simply require this package in your code by writing :

Now you can easily use PUT and DELETE routes :

HTTP verbs: Some of the common HTTP methods/verbs are described below:

• GET: Retrieves one or more resources identified by the request URI and it can cache the information receive.
• POST: Create a resource from the submission of a request and response is not cacheable in this case. This method is unsafe if no security is applied to the endpoint as it would allow anyone to create a random resource by submission.
• PUT: Update an existing resource on the server specified by the request URI.
• DELETE: Delete an existing resource on the server specified by the request URI. It always return an appropriate HTTP status for every request.
• GET, PUT, DELETE methods are also known as Idempotent methods. Applying an operation once or applying it multiple times has the same effect. Example: Delete any resource from the server and it succeeds with 200 OK and then try again to delete that resource than it will display an error message 410 GONE.
