    These days the Internet has become one of the basic needs of a human being. Every digital device is ready to be a part of the internet. From watches to smartphones, the internet is everywhere. So, to make the internet secure and more efficient, there are many protocols (set of rules followed by the internet) associated with it. Here in this article, we will discuss one of the most important internet protocols i.e. HTTP.

    What is HTTP?

    HTTP full form is HyperText Transfer Protocol , by its name we can guess this protocol is for transferring HyperText. HTTP is an application protocol, used by WWW (World Wide Web).  This protocol is used to set communication between the client and the server. It collects the HTTP request from the client and sends this request to the server and in response, the server sends an HTTP response back to the client. Due to its simplicity WWW adopt this protocol for the web pages.

    What is HTTPS?

    Whenever we use our web browser to visit a website so on the search bar, we could see HTTP or https before the domain name of any website. HTTPS stands for HyperText Transfer Protocol Secure whereas S stands for secure which means, a particular website is secure to visit and does not save any kind of malicious data.

    HTTP Request Methods

    As HTTP works on the request and response model, a client has many HTTP request methods to request the server for a response.

    • GET

    The GET request fetches data from the client and includes it on the URL portion of the request.

    • HEAD

    It is similar to the GET request but it doesn’t have any response body. The Head request is mostly used to retrieve meta-information written in the response header.

    • POST

    It has the same working as the GET method but it does not save the data, instead directly sends it to the server.

    • PUT

    We use the PUT method to store enclosed data to a specified or supplied URL

    • DELETE

    We use the DELETE method to delete the specific resource

    • TRACE

    This method is used to echo the request, so the client can see the changes in the server.

    • OPTIONS

    This method checks the functionality of the webserver.

    • CONNECT

    It converts the request connection to transparent TCP/IP
