Subject: Detecting open Anonymous Web Proxies

I am probably attempting the impossible but am hopeful that I can find a
solution that might be "good enough".  I am trying to detect if a visitor to
a website is accessing it through a Web Proxy redirector.

We manage a couple free gaming web forums visited mostly by adolescents and
kids being kids there are occasional problems that require preventing
access, a process hampered by the use of web proxies.  In addition we are
also trying to limit access to the web forum from school networks which are
often bypassed by kids using web proxies.

My research has turned up a couple of possible solutions. The first is
detecting the HTTP header information sent by the client the second is to
use some type of IP list.

So hence my questions:

1) Is there anyway to obtain/read the HTTP header information sent by the
client with Cold Fusion 5? 

2) Does anyone know of a database of known anonymous Web proxy IP numbers
and either a legitimate project to keep it maintained or a real reliable
company that offers it as a subscription service?


I am also open to other ideas as well.



Best Regards,
