# Testing for Host Header Injection

## When to Use
- When testing password reset functionality for token theft via host manipulation
- During assessment of web caching behavior influenced by Host header values
- When testing virtual host routing and server-side request processing
- During penetration testing of applications behind reverse proxies or load balancers
- When evaluating SSRF potential through Host header manipulation

## Prerequisites
- Burp Suite for intercepting and modifying Host headers
- Understanding of HTTP Host header role in virtual hosting and routing
- Knowledge of alternative host headers (X-Forwarded-Host, X-Host, X-Original-URL)
- Access to an attacker-controlled domain for receiving poisoned requests
