What is the Purpose of HTTP Protocol? A Comprehensive Guide

The Hypertext Transfer Protocol, or HTTP, is the backbone of data communication on the World Wide Web. But what is the purpose of HTTP protocol? In short, it defines how messages are formatted and transmitted, enabling web browsers and servers to exchange information seamlessly.

Core Functions of HTTP

HTTP operates as a request-response protocol between a client and server. It allows fetching resources, such as HTML documents, and supports features like caching and cookies to enhance user experience.

Stateless Protocol Design

Each HTTP request is independent, meaning no session information is retained. This simplicity supports scalability but requires additional mechanisms like cookies for state management.
