HTTP
Domain: Computer Systems
🎯 Motivation
HyperText Transfer Protocol - the protocol of the web. Browsers send HTTP requests, servers send HTTP responses.
📋 Concrete Example
HTTP request: ‘GET /api/users HTTP/1.1’. Response: ‘200 OK, Content-Type: application/json, Body: [{name: Alice}]’. Every web page load is an HTTP request-response.
🔗 Analogy
HTTP is like ordering at a restaurant - you (browser) say ‘I want the menu’ (GET /menu). The waiter (server) brings it. HTTP defines the format of these requests and responses.
