Hallo, squid-users, I'm testing squid-3.1.0-20110131. I'm trying authentification. When authentification (ncsa or smb) fails then "errors/errorpage.css" ("/etc/squid/errorage.css") seems to be invoked. And in this *.css the address of the background picture (SN.png) leads to the "www.squid-cache.org" site. But because authentification has failed this site is unreachable. The proposed picture (SN.png) should be copied to "/usr/share/squid/ icons", and the proposed *.css link should set to this local address. Viele Gruesse! Helmut
