HTTP Headers Mastery Handbook – Web Penetration Testing & Security Headers Guide

Every HTTP request and response you'll ever intercept in Burp Suite is wrapped in headers. This handbook teaches you to read them like a professional penetration tester — extracting intelligence, spotting misconfigurations, and exploiting attack surface that most testers walk straight past.

What's inside:

• Live Burp Suite capture dissected line by line — every request & response header explained
• Request headers deep dive — Host, Origin, Referer, Content-Type, Sec-Fetch, X-Lab-Token and more
• Response headers deep dive — CORS headers, Cache-Control, HSTS, ETag, Server disclosure
• Security headers audit — what protects a site and what's missing (CSP, X-Frame-Options, Referrer-Policy)
• Custom & non-standard headers — X-Forwarded-For, X-Powered-By, X-RateLimit and what they reveal
• 4 exploitation techniques — CORS misconfiguration, Host header injection, IP spoofing, Content-Type CSRF bypass
• Reading & editing headers in Burp Suite — full workflow
• Complete quick reference table — every header, direction, and attack potential in one place
• Student exercises + discussion questions

Who it's for: Bug bounty hunters, penetration testing students, developers building secure APIs, and anyone who wants to stop guessing what headers do and start exploiting them.
