Hi folks, My Squid always modifies the X-Forwarded-For header with the client-IP. I'm now in a situation I want to keep the X-Forwarded-For header as it is.. As far as i see it's only possible to disable the X-forwarded-for header, which will result the header as: X-Forwarded-For: Unknown. At this time, I have already a X-Forwarded-For header. My final header as Squid will send out is: X-Forwarded-For: <my-client-ip-by-other-squid>, <other proxy server> I want Squid to keep the header for what it is, thus: input: X-Forwarded-For: <my-client-ip-by-other-squid> ouput: X-Forwarded-For: <my-client-ip-by-other-squid> Is this possible? Thanks, Janno.
