Hi all, I have many users using squid2.6 stable18 version. There are many users who need access to sites like youtube, onlinemovies etc.. but, i have to block access to these sites for other users and all of them are online at the same time. I have used acl badurl url_regex -i teen orkut youtube sex mp3 mp4 exe in my squid.conf. Can i use unix groups to achieve this? Say for example, create acl's for users in a particular group and give them access external_acl_type unix_group %LOGIN /usr/lib/squid/squid_unix_group -p acl staffgroup external unix_group staff Users in staff group should have access to youtube etc.. How do i do this? Thanks Avinash
