[squid-users] Upstream Proxy

They're very vague and not helpful. It was said they look for email, but in reality it would be user at blah.company.com rather than user at company.com.

This is the only information I have for them.

What HTTP authentication method(s) or scheme(s) does your upstream proxy support or require?

This is not my area of expertise, but the above error message suggests that the proxy wants to do HTTP Basic authentication, but you are configuring Squid to use NEGOTIATE, so perhaps you should switch to Basic as the next step in your triage, just to get something working (cache_peer ... login=user:password)?

Sharing what CONNECT request headers Squid sends to the parent proxy may be useful as well, but do not use any secrets in your test traffic if you are going to share such details. If you still have that cache.log, look for "Tunnel Server REQUEST" associated with conn2126.

HTH,

Alex.
