Hi Amos, Thanks for the prompt reply. I'm trying to get squid to use the same headers as it received (to make it more transparent) so I would like to understand how it works so I can figure out how to configure it that way. After looking up online I configured the following: request_header_access Authorization allow all request_header_access Proxy-Authorization allow all request_header_access Cache-Control deny all request_header_access Content-Length allow all request_header_access Content-Type allow all request_header_access Date allow all request_header_access Host allow all request_header_access If-Modified-Since allow all request_header_access Pragma allow all request_header_access Accept allow all request_header_access Accept-Charset allow all request_header_access Accept-Encoding allow all request_header_access Accept-Language allow all request_header_access Connection allow all request_header_access All deny all I also have the following configs in addition: via off forwarded_for delete Is there any way to have squid generate the exact same headers as it received? -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Does-squid-generates-adds-additional-HTTP-headers-tp4683050p4683052.html Sent from the Squid - Users mailing list archive at Nabble.com. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
