I have run in to this odd issue that appears to be only specifically related to AOL and their login service. This affects anyone attempting to login to AOL webmail and their other "walled garden" actions that require one to be logged in before being offered the requested service. What happens is when one surfs to http://webmail.aol.com/ they are redirected to the AOL mail login screen, which has a javascript based form on the right-hand side of the page. When a user enters their screen name and password and then clicks "sign-in" the page refreshes a couple times and ultimately stops at the following URL: http://registration.aol.com/_cqr/login?sitedomain=registration.aol.com&authLev=1&siteState=OrigUrl%3Dhttp%253a%252f%252fregistration%252eaol%252ecom%252fmail%253fs%255furl%253dhttp%25253a%25252f%25252fwebmail%25252eaol%25252ecom%25252f%25255fcqr%25252fLoginSuccess%25252easpx%25253fsitedomain%25253dsns%25252ewebmail%25252eaol%25252ecom%252526siteState%25253dver%2525253a1%252525252c0%25252526ld%2525253awebmail%25252eaol%25252ecom%25252526pv%2525253aAOL%25252526lc%2525253aen%25252dus%25252526ud%2525253aaol%25252ecom%25252526br%2525253aWebSuite%25252dCurrentProd&lang=en&locale=us&uitype=mini&_sns_bg_color_=b8d2e5&_sns_fg_color_=000000&_sns_err_color_=FF0000&_sns_link_color_=000000&mcAuth=%2FBcAG0V6BvoAAK9MA4B8TEV6BzYI4062lHNvp3IAAA%3D%3D This page displays nothing. It never redirects the user back to their webmail inbox or any other portion of AOL, nor does AOL ever show the user logged in. The browser (IE and Firefox both) merely depict a blank page with nothing.

NETWORK\username DIRECT/64.12.129.11 - If we run these requests through an ISA Server as a test then the pages display properly. I am assuming that ISA is rewriting something that causes the pages to display as planned. We are running Squid 2.6.STABLE3 with integrated AD authentication. Does anyone have any ideas what might be going on and have any ideas for fixing this? Regards, Scott
