What is the Purpose of HTTP Protocol? A Comprehensive Guide

The Hypertext Transfer Protocol (HTTP) is the foundational protocol for data communication on the World Wide Web. It defines how messages are formatted and transmitted, enabling browsers and servers to interact seamlessly.

Core Functions of HTTP

HTTP facilitates client-server communication, allowing web browsers (clients) to request resources like HTML pages, images, or data from web servers. Its stateless nature ensures each request is independent, simplifying server design while supporting cookies for session management.

Request-Response Model

Using methods like GET, POST, and PUT, HTTP handles data retrieval, submission, and updates. Status codes (e.g., 200 OK, 404 Not Found) provide immediate feedback on request outcomes.

Security and Evolution

HTTP has evolved into HTTPS with encryption via SSL/TLS, protecting data integrity and privacy—critical for e-commerce and secure logins.
