Hypertext Transfer Protocol (HTTP) is an application-layer protocol for transmitting hypermedia documents, such as HTML. It was designed for communication between web browsers and web servers, but it can also be used for other purposes.
An HTTP request has three parts: the request line, the headers, and the body of the request (normally used to pass form parameters).
Both GET and POST method is used to transfer data from client to server in HTTP protocol but Main difference between POST and GET method is that GET carries request parameter appended in URL string while POST carries request parameter in message body which makes it more secure way of transferring data from client to ...
HTTP Responses Common status codes are 200 , 404 , or 302. A status text. A brief, purely informational, textual description of the status code to help a human understand the HTTP message.
How does HTTP work? As a request-response protocol, HTTP gives users a way to interact with web resources such as HTML files by transmitting hypertext messages between clients and servers. HTTP clients generally use Transmission Control Protocol (TCP) connections to communicate with servers.

Simply put, HTTP is the protocol that enables communication online, transferring data from one machine to another. WWW is the set of linked hypertext documents that can be viewed on web browsers (such as Firefox, Google Chrome, and more).
The GET Method
PUT method is call when you have to modify a single resource, which is already a part of resource collection. POST method is call when you have to add a child resource under resources collection. RFC-2616 depicts that the PUT method sends a request for an enclosed entity stored in the supplied request URI.
“What happens when you type in a URL” is a deceptive question commonly asked in tech interviews. ... You enter a URL into a web browser. The browser looks up the IP address for the domain name via DNS. The browser sends a HTTP request to the server.
Summary of HTTP Methods for RESTful APIs
An application implementing a RESTful API will define one or more URL endpoints with a domain, port, path, and/or querystring — for example, https://mydomain/user/123?format=json . Examples: ... a PUT request to /user/123 updates user 123 with the body data. a GET request to /user/123 returns the details of user 123.
A RESTful API is an architectural style for an application program interface (API) that uses HTTP requests to access and use data. That data can be used to GET, PUT, POST and DELETE data types, which refers to the reading, updating, creating and deleting of operations concerning resources.
In computing, the PATCH method is a request method supported by the Hypertext Transfer Protocol (HTTP) protocol for making partial changes to an existing resource. The PATCH method provides an entity containing a list of changes to be applied to the resource requested using the HTTP Uniform Resource Identifier (URI).
POST is always for creating a resource ( does not matter if it was duplicated ) PUT is for checking if resource is exists then update , else create new resource. PATCH is always for update a resource.
Using PUT requires us to specify all attributes even if we want to change only one attribute. But if we use the PATCH method we can update only the fields we need and there is no need to mention all the fields. PATCH does not allow us to modify a value in an array, or remove an attribute or array entry.
The HTTP PUT method is used to update an existing record in the data source in the RESTful architecture. So let's create an action method in our StudentController to update an existing student record in the database using Entity Framework. The action method that will handle HTTP PUT request must start with a word Put.
In GET method, values are visible in the URL while in POST method, values are NOT visible in the URL. GET method supports only string data types while POST method supports different data types, such as string, numeric, binary, etc. ... GET request is often cacheable while POST request is hardly cacheable.
Use an HTTP POST request to send single or multiple RPC requests to the REST API....For both single and multiple RPC commands, HTTP Accept headers can be used to specify the return format using one of the following Content-Type values:
Let us begin the code step by step.
CRUD stands for Create, Read, Update, and Delete, which are four primitive database operations. At first glance, these operations map well to the HTTP verbs most frequently used in REST: Create (SQL INSERT) : POST - Used to support the creation of a child resource, but can also modify the underlying state of a system.
From a RESTful service standpoint, for an operation (or service call) to be idempotent, clients can make that same call repeatedly while producing the same result. In other words, making multiple identical requests has the same effect as making a single request. ... The PUT and DELETE methods are defined to be idempotent.
Yes, you can make it work at least using WCF, it's bit different in MVC and Web API where you add attributes to methods like [GET] [POST] etc.. ... Off course it is bad practice to use POST for getting data as POST is for creating resources in system not getting them.
The GET and POST are two different types of HTTP requests. GET is used for viewing something, without changing it, while POST is used for changing something. For example, a search page should use GET to get data while a form that changes your password should use POST .
GET is slightly faster because the values are sent in the header unlike the POST the values are sent in the request body, in the format that the content type specifies.
POST is valid to use instead of GET if you have specific reasons for doing so and process it properly.
