And I do > mean ANYONE, anywhere on the net. I've said I am a newbie :-) So, how should I write this one? I found the example on the internet and tought it would be right. >> http_access allow localhost >> http_access deny blockcache AuthUser >> http_access allow allowedurls AuthUser >> acl lunchbreak time D 13:00-14:00 >> acl lunchbreaksites dstdomain "/etc/squid/lunchbreaksites" >> http_access allow lunchbreak lunchbreaksites >> > So far it looks okay. Those are all everyone-or-nobody right? Exactly, we have caching sites like google and yahoo in "blockcache" file and sites everyone can see in "allowedurls". Same for "lunchbreaksites", everyone during this period can see those sites. >> # User by user ACL: >> >> acl administrator proxy_auth REQUIRED >> acl assistenza proxy_auth REQUIRED > > Here is where the problems start. > 'REQUIRED' means only that the person MUST login.

Right now I think we will use the internal list in squid.conf, since we have not so many users, but I'll try also the sexternal_acl, so I can learn something for the future!!! I will let you know about the tests. Luca.
