HTTP Request & Response

HTTP Request & Response

HTTP (HyperText Transfer Protocol) is the foundation of data exchange on the web. It follows a request-response model where a client sends a request and a server returns a response.

HTTP Request Structure

Host: www.example.com
User-Agent: Mozilla/5.0
Accept: text/html

A request has:

• Request line: method, path, HTTP version
• Headers: key-value pairs
• Body (optional, for POST/PUT)

HTTP Response Structure

HTTP/1.1 200 OK
Content-Type: text/html
Content-Length: 13
