Episode 22 — Understand HTTP Mechanics Clearly: Methods, Headers, Cookies, and Sessions
This episode builds a clean, exam-ready understanding of how HTTP works and why web mechanics are a security topic, not just a developer concern. You’ll review common methods like GET and POST, then connect method choice and idempotence to risks such as unintended state changes, caching mistakes, and insecure endpoints. We’ll break down headers that shape security posture, including Host, Authorization, Content-Type, and caching controls, and we’ll explain how cookies and session tokens actually create state on top of a stateless protocol. Real-world scenarios include session hijacking through stolen cookies, insecure flags that enable client-side access, and proxy behavior that changes what the server sees as the source. Troubleshooting considerations include distinguishing application errors from transport issues, spotting misconfigured redirects, and recognizing when “it works in one browser” points to cookie scope, SameSite behavior, or mixed content blocking.
