All, Several of our users are trying to access a web site, and squid seems to have a problem with it. Here's a munged log line (the client computer name and my $WORK name have been changed, but nothing else): 192.168.12.59 sales1.example.com 66.173.42.248 [25/Aug/2010:09:22:28 -0700] "GET http://portal.geo-comm.com/sites/example HTTP/1.1" 401 1979 "-" "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; .NET4.0C; .NET4.0E)" TCP_MISS When we browse with either IE or FF, and use the squid proxy, we get a 401.2. If I then open up an exception on the firewall and they browse direct, they get a popup asking for credentials (ID/Password), and the site works. I'm not sure how I'd go about troubleshooting this, or fixing it. Anyone have some thoughts on what might be happening? Thanks, Kurt
