My test also worked, using Squid 3.1.10. My best guess is "Connection-Pinning", a feature that does not exist in 2.5 or 3.0 branches. Please attempt to upgrade to either 2.7 or 3.1 branches, and see if that works. >>> "JC Putter" <jcputter@xxxxxxxxxxxx> 3/2/2011 11:05 AM >>> mmm... did you say the popup does not appear then using squid?

When surfing out of squid, auth popup opens well. I tested out through a lot of different machines running different versions of squid, same issue. I'm not an expert and logs do not tell me what to do... Has anyone ever seen this? Is it possible to post the url here if someone wants to give it a try?
