## **How HTTP Works: A Step-by-Step Overview**
When you type a URL into your browser, an HTTP request is sent to the server hosting the website. The server processes your request and returns the appropriate response—usually the webpage you want to see. This request-response model makes HTTP a stateless protocol, meaning it doesn’t retain information between sessions.
### **Key Components of HTTP**
– **HTTP Requests**: Methods like GET, POST, PUT, DELETE.
– **HTTP Responses**: Status codes such as 200 (OK) or 404 (Not Found).
– **Headers**: Carry metadata about the request or response.

**Is HTTP still used today?**
Yes, though HTTPS is now the standard for secure sites, HTTP is still common in development and local networks.
**Why is HTTP called a stateless protocol?**
It doesn’t store user data between requests, which simplifies server design but requires other methods (like cookies) for tracking sessions.
