What is the Purpose of HTTP Protocol? A Complete Guide

The Hypertext Transfer Protocol (HTTP) is the foundation of data communication on the World Wide Web. It defines how messages are formatted and transmitted, enabling interactions between clients and servers.

Core Functions of HTTP

HTTP facilitates request-response interactions between clients (like web browsers) and servers. Its main purpose is to fetch resources such as HTML documents, images, and APIs efficiently.

Stateless Protocol Mechanism

HTTP is stateless, meaning each request is independent. This simplifies server design but requires sessions or tokens for state retention in applications.

Status Codes and Error Handling

It uses status codes (e.g., 200 OK, 404 Not Found) to communicate outcomes, ensuring reliable data exchange and user feedback.
