is it possible to get Squid 2.6 to authenticate in transparent mode?
I set it up to run in transparent mode and defined an auth_param basic program, but Squid seemed to ignore the authe_param entry. is
this correct behavior?
The browser never asks the proxy because it cannot know there is a proxy
at work. Thus authentication in transparent mode cannot work. Either you
have to configure you browsers to user the proxy (and prevent direct
internet access using a firewall) or you cannot use proxy auth.
