 If you want to filter HTTP or HTTPS you can try apache's 
mod-security module (http://www.mod-security.org/)

 For protocls such as edonkey or ftp have look at l7 Filter 
(http://l7-filter.sourceforge.net). They says it works at 7th Layer. 
So you may be able to filter all well known protocols. I haven't 
tried it. So, feedbacks are welcome !
