# Pentest HTTP Smuggling

## Purpose
Detect and exploit discrepancies between front-end proxies and back-end servers in HTTP request parsing. These attacks bypass security controls, poison caches, and hijack requests — entirely absent from standard taint analysis pipelines.

## Prerequisites

### Authorization Requirements
- **Written authorization** with explicit scope for protocol-level testing
- **Infrastructure awareness** — identify all reverse proxies, CDNs, load balancers in path
- **Rollback plan** for cache poisoning tests (CDN purge access)
- **Emergency contacts** for infrastructure team (smuggling can affect other users)

### Environment Setup
