Hello, I faced a strange problem after upgrading from squid-2.4.STABLE1 -> 2.5.STABLE12. I have authentication for all users, but there are a few sites which do not need authentication. For the authentication the conf file contains the followings: acl all src 0.0.0.0/255.255.255.255 acl authenticate proxy_auth_regex \* acl PROXY src <the server IP address>/255.255.255.255 acl noauth dstdomain "/usr/local/squid/etc/noauth_web.txt" http_access allow noauth http_access allow authenticate !PROXY http_access allow all The noauth_web.txt contains the web sites which don't need authentication. (The authentication goes well, and the sites, which don't need authentication, could be reached too without authentication through the login window.) My problem is: when the user logs in and calls for a site which doesn't need authentication the new squid pops up the login window, to reach the content of this site the user has to to click on the "cancel" button. In the old version of squid there was no pop up window if a site, listed in the noauth_web.txt file, was called. The content of the site was displayed directly. I tried to find out what could cause the problem, but can't. Could someone help me please, how to configure squid to eliminate the pop up window when it is not needed? Thanks in advance. Best regards, Zsolt Sandor
