What is HTTP Protocol? A Comprehensive Guide for Beginners

Have you ever wondered how your browser fetches websites so quickly? It’s all thanks to the HTTP protocol, the backbone of data communication on the web.

Understanding HTTP Basics

HTTP, or Hypertext Transfer Protocol, is a set of rules for transferring files online. When you enter a URL, your browser sends an HTTP request to a server, which responds with the requested data.

How HTTP Works

It operates as a request-response protocol between clients and servers. For example, clicking a link triggers a ‘GET’ request, and the server replies with the webpage content.

Key Features of HTTP

HTTP is stateless, meaning each request is independent. It also supports various methods like POST for form submissions and headers for metadata.

Common HTTP Status Codes

You might recognize codes like 404 Not Found or 200 OK. These indicate request outcomes, helping debug issues.
