I'm running squid 2.6 on windows 2003 and it works perfectly apart the following problem: In order to block porn sites I used dstdomain acl porn dstdomain "c:/squid/block/pornblock.txt" And in c:/squid/block/pornblock.txt I added urls like these: .playboy.com .superfiga.com .... The problem is that SOMETIMES (not always!) squid prompt for username/password because I think some sites that contains one of the above words are blocked while I need to block only ENTIRE URLS and not those matching a word contained in this file. I'm sure the problem is related to this acl because disabling this acl the problem doesn't apper Example: I want to block only www.playboy.com or www.superfiga.com but NOT www.mysite.playboy.com or www.ciao.superfiga.com I assure that before write in this mailing list I read tons of documentation in internet but I didn't find a solution What is wrong? Can someone at leaste give me a suggestion please? Thanks Marco Italy
