However, I have downloaded and installed "Squid Cache: Version 3.HEAD-20080424", and in the config, I set forwarded_for truncate However, I still see my cheated XFF exist in my backend PHP program, e.g. [HTTP_X_FORWARDED_FOR] => 192.168.11.103 [Cheated using FF Modify Header] [REMOTE_ADDR] => MY_SQUID_IP (I know I might need to do a TCP dump in my apache server, hopefully tomorrow.)
