I have an external site that requires authentication that's not working through my proxies. The squid versions vary from 2.6.STABLE6 to 2.6.STABLE13 with the same results. With IE7, all that's returned is "cannot display the webpage" even with "show friendly http error messages" turned off. With FF2, the login box keeps popping up until you cancel. Here's the oddity though, I have one XP machine that is able to authenticate through the proxy without any problems with both IE7 and FF2. Same user, same proxy, same passwords just different machines. If I bypass the proxy, everything works fine on all machines. I read something in the archives about configuring the browser to keep authentication details longer. Could that be the difference? If so, I have no idea how to change that?? Below are the two relevant portions from access.log. I have the live http header add-on for FF also but I'm ignorant on reading and using it effectively. Any help or ideas are appreciated!
