HTTP and the Web Request–Response Model

Learn how every web interaction is an HTTP request and response — methods, paths, status codes, headers, and cookies — by watching a real Juice Shop login in the Network panel.

Before we begin, here is exactly what you will be able to do by the end of this lesson.

By the end of this lesson, you will be able to:

  • Identify the method, path, status code, request headers, cookies, and body within an HTTP request and response.
  • Distinguish between "safe" methods (GET) that must not change state and state-changing methods (POST, PUT, DELETE).
  • Read HTTP status-code families at a glance: 2xx success, 3xx redirect, 4xx client error, 5xx server error.
  • Explain why HTTP is stateless, and describe how session cookies and bearer tokens maintain a session across separate requests.
