Hi Andrew, I don't have any specific recommendation for you however from my aquintance with this family of products, most of them, perform url filtering using some blacklist. What they really should do is perform content filtering based on the information recieved from the server rather then the url list. Currently you can bypass most of these products utilizing a web proxy, needless to say, proxies are abundant on the WWW and each day you have new ones from all over the world so its practically impossible to keep track of all of them. Its a tough problem and I believe that some vendors are on it now trying to provide a solution (and if not then here's your chance... :-)).

Currently the company I work for currently uses DansGuardian <http://dansguardian.org/> for our web content filtering, but we are having a problem with people using CGI/PHP proxies (such as the ones below) to bypass it. Websense <http://www.websense.com> seems to be the gold standard in content filtering, but the price on it would really hit our budget hard. Does anyone here have something cheaper that I should take a look at? Here are some of the CGI/PHP proxies we have discovered users utilizing to bypass our content filtering: <http://56st.com> <http://www.proxysf.com> <http://blackip.info> -aws
