Well, Squid can certainly receive that header and a Squid helper or adapter can interpret it, even providing authentication-like capability if needed. Please note that I am not trying to defend the use of that header for anything, just indicating that some related functionality is available even though Squid itself does not treat X-Forwarded-User specially.
