What is HTTP - HyperText Transfer Protocol?

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 (sets 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 adopts this protocol for web pages .

What is HTTPS?

Whenever we use our web browser to visit a website so, on the search bar, we can 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 that the client can see the changes in the server.

• OPTIONS

This method checks the functionality of the web server.

• CONNECT

It converts the request connection to transparent TCP/IP
