Abusing HTTP hop-by-hop request headers
Naming arbitrary headers in the HTTP Connection header marks them hop-by-hop, and proxies that forward that list instead of consuming it let an attacker delete headers a downstream hop added. Removing X-Forwarded-For can make an application treat the request as internal, and the trick also fingerprints caches, bypasses WAF rules that require a header, and can poison caches with error responses.
