If so try adding login=PASSTHRU to the cache_peer lines. That will send the users credentials to it. Otherwise login= can be used with an explicit login user:passwd to be sent to the peer server. > > 2. I launch https://x.domain.com and authenticate. It lets me in.

And no there is no way to get around that. It is a requirement of web security that login credentials are scoped by domain and are not permitted to be delivered to any other. There is no reason to expect any two differently named domains use the same authentication backend even if they are contacted through the same proxy or even hosted on the same IP:port.

Firfox and Chrome are getting rather pedantic about some of those errors nowdays. To the point where user override is no longer possible on certain warnings. They just refuse to connect to the server. Amos
