HTTP Method


HTTP Status Code Difference Between Http and Https

What are HTTP Method

HTTP (Hypertext Transfer Protocol), is the underlying format that is used to structure request and responses for effective communication between a client and a server. The message that is sent by a client to a server is what is known as an HTTP request.

The Hypertext Transfer Protocol (HTTP) is designed to enable communications between clients and servers. HTTP works as a request-response protocol between a client and server. Example: A client (browser) sends an HTTP request to the server; then the server returns a response to the client. The response contains status information about the request and may also contain the requested content.

Types of HTTP Request Methods

GET: GET is used to retrieve and request data from a specified resource in a server. GET is one of the most popular HTTP request techniques. In simple words, the GET method is used to retrieve whatever information is identified by the Request-URL.



POST: POST is used to send data to a server to create/update a resource. The data sent to the server with POST is stored in the request body of the HTTP request.


POST /test/demo_form.php HTTP/1.1

DELETE: Removes all the current representations of the target resource given by URI.

PUT: Replaces all the current representations of the target resource with the uploaded content.

HEAD: Same as GET, but it transfers the status line and the header section only.

CONNECT: Establishes a tunnel to the server identified by a given URI.

OPTION: Describe the communication options for the target resource.

TRACE: Performs a message loop back test along with the path to the target resource.
