Proxy-authentication cannot be performed on MITM'd traffic. That
includes SSL-bump decrypted messages.
However, unlike the other methods SSL-bump CONNECT wrapper messages in
explicit-proxy traffic can be authenticated and their credentials
inherited by the messages decrypted. Squid should be doing that. But
again cannot do it for the fake/synthetic ones it generates itself on
intercepted port 443 traffic.
So the question becomes, why are foo and bar ACLs not matching?
http_access rules are applied separately to the CONNECT wrapper message
and to the decrypted non-CONNECT HTTP message(s).
