I am trying to run proxy server for my small office network.
So I am currently configuring the /etc/squid/squid.conf file for setting up my server as a proxy server. I want to block all the phono/sex sites coming into the office network. So there is a way to block the destination sites based on regular expressions in squid.conf file. I am trying to block all the sites having the keyword sex in the url.

acl Sex url_regex sex
acl Sex1 urlpath_regex sex
acl Sex2 dstdom_regex sex
http_access deny Sex Sex1 Sex2

Instead of giving the above three definitions the browser allows the url paths with the keyword sex. Please help me resolve this issue.
Thanks in advance.

Do you not need -i in there, such as "acl Sex url_regex -i sex"? I'm not too hot with regular expressions through Squid. Instead, run DansGuardian inline with Squid to provide true content filtering. Think of how many websites don't contain "sex" in the url that would sail through. Using the ACL's like you have you'd only catch a handful of sites. SquidGuard would be a bit easier at blocking direct URL's, but not scanning the content of sites before providing them to end-users.
