Subject: Proxies

It is more or less impossible with current technology
to set up an automated system to *completely* prevent
users from accessing certain HTTP content. What I mean
here is that everything available can be bypassed. 

How do you block *all* HTTP proxies, for instance(a la
Surfola and party)? How about custom written CGI
proxies? How about JAP like software?

IMHO, these kind of measures are the only thing you
can do to enforce your content access policies.
