What is the Purpose of HTTP Protocol? A Complete Guide

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

Core Functions of HTTP

HTTP facilitates request-response interactions between clients (like web browsers) and servers. It allows fetching resources such as HTML documents, images, and APIs, ensuring structured data exchange over networks.

Stateless Protocol Design

Each HTTP request is independent, meaning no session information is retained by the receiver. This simplicity enhances scalability and reliability, though sessions are often managed via cookies or tokens.

Status Codes and Methods

HTTP uses status codes (e.g., 200 OK, 404 Not Found) and methods (GET, POST) to communicate request outcomes and actions, streamlining error handling and user experience.

FAQs
