Dear all, My squid box contained : ntlm_auth + CentOS + squid 2.7. It's work fine for authenticate over windows 2003 AD. But, in some case, my user use some website such as http://www.apple.com/quicktime/download/, this webpage contain external link in download session. Let's me explain the problem into step by step - My user open new safari or IE browser - He connect to http://www.apple.com then he put his login/password into pop-up windows. - After login, it's ok to open page that contain http://www.apple.com/. - Then he click to "Download Quicktime"(http://www.apple.com/quicktime/download/). The new pop-up window is opened. It's three time of login progress. I think url http://www.apple.com/quicktime/download/ should has 3 external links. So squid think that use reopen new session than it try to recheck login/password. Any idea about fix this problem ? I don't know that other browser act like above problem? Thanks Chong
