What is HTTP?

HTTP (Hypertext Transfer Protocol) is the foundation of data communication on the World Wide Web. It is a protocol that defines how messages are formatted and transmitted between a client (usually a browser) and a server. When you visit a website, your browser sends an HTTP request to the server hosting the website, and the server responds with the requested content (like HTML, images, or videos).

Key Features of HTTP:

1. Stateless:
HTTP does not retain any information about previous requests. Each request is treated as independent.

2. Client-Server Model:
Communication is initiated by the client and responded to by the server.

3. Methods:
HTTP uses methods like:

GET: Request data from the server.

POST: Send data to the server.

PUT: Update data on the server.

DELETE: Remove data from the server.

4. URL Structure:
HTTP works with URLs (Uniform Resource Locators) to identify resources on the web.

HTTP vs. HTTPS:
While HTTP is the standard protocol, HTTPS (HTTP Secure) is a secure version that encrypts data using SSL/TLS, ensuring privacy and data integrity.

Why is HTTP Important?

HTTP is the backbone of the web, enabling browsers and servers to communicate seamlessly. It’s lightweight, extensible, and essential for delivering content across the internet.
