performing-web-cache-deception-attack
Executes web cache deception attacks by exploiting path normalization discrepancies between CDN/reverse-proxy caching layers (Cloudflare, Akamai, Varnish, Nginx) and origin servers to cache and retrieve sensitive authenticated content. Use when testing applications behind CDNs for cache-key misconfigurations, during bug bounty hunting on aggressively cached sites, or when assessing sensitive data exposure through cache layer misconfiguration.

# Performing Web Cache Deception Attack
## When to Use
- When testing applications behind CDNs or reverse proxies (Cloudflare, Akamai, Varnish, Nginx)
- During assessment of authenticated page caching behavior
- When evaluating path normalization differences between caching and origin layers
- During bug bounty hunting on applications with aggressive caching policies
- When testing for sensitive data exposure through cache layer misconfiguration
## Prerequisites
- Understanding of HTTP caching mechanisms (Cache-Control, Vary, Age headers)
- Knowledge of CDN path normalization and cache key construction
- Burp Suite for intercepting and crafting requests
- Two browser sessions (authenticated victim and unauthenticated attacker)
