[squid-users] newbie on squid-cache

Hello,
it's the first time I'm configuring squid and I have a little question about
ACL.
I would like to deny http_access to my users to web sites containing words
in the url like SEX YOUNG ... everything that is not in relation with the
work.
I have found the way to deny http_access to some sites giving th explicit
URL, but how can I do the deny access to URL in witch I can found some words
?

http_access deny mygroup .SEX.
http_access deny mygroup ?.SEX.?
http_access deny mygroup %.SEX.%

I'm french and I may I have not anderstand completly the documentation.

Can somebody tell me how to do that.

Thank you.
