What Is HTTP Protocol? A Comprehensive Guide

In today’s digital world, the what is http protocol question is fundamental to understanding how the web works. HTTP, or Hypertext Transfer Protocol, is the backbone of data communication on the internet. This guide explains everything you need to know.

Understanding HTTP Protocol Basics

HTTP is an application-layer protocol designed for transmitting hypermedia documents, like HTML. It follows a client-server model, where a web browser (client) sends a request to a server, which then returns a response.

How HTTP Requests and Responses Work

When you enter a URL, your browser sends an HTTP request to the server. The server processes it and sends back the requested resource, along with a status code (e.g., 200 OK or 404 Not Found).

Key Features of HTTP

HTTP is stateless, meaning each request is independent. It’s also extensible, allowing headers to customize requests. Modern HTTP supports secure connections via HTTPS.

HTTP Methods: GET, POST, PUT, DELETE

These methods define the action to be performed. GET retrieves data, while POST submits data to the server.
