I have created to groups of users to access the internet through the proxy. We would like to log down 1 of the group only, but in the access.log, it has both groups in it. Can anyone tell me how I can filter out the other group that I don't want to log down? These are what I have in my squid.conf file acl HK src 192.188.1.1-192.188.1.254/255.255.255.0 acl CHINA src 192.168.1.1-192.168.1.254/255.255.255.0 acl CHINA2 src 192.168.2.1-192.168.2.254/255.255.255.0 acl user proxy_auth user1 user2 user3 acl ChinaUser proxy_auth user4 user5 user6 acl TIME time ident_lookup_access allow CHINA HK CHINA2 TIME ChinaUser Thanks Regards William
