Please help me detect proxy servers

[Floortje]

Hi, I have got a huge problem. I maintain a forum om my website
www.cavalierpage.com on the dog breed cavalier king charles spaniel. For the
past few weeks someone has been terrorizing my page from anonimous proxy's.
Maybe needless to say that there are thousends of them so I can hardly block
them all.

I read somewhere that java can detect the proxy settings of a user and
preferably the real ip (and then send them to my server or add them as a
hidden variable etc). I know next to nothing about java. Are there any good
tutorials for a noob that will explain to me how I can achieve this ?
Offcourse I googled but that didn;t give me the info I needed. Most of it
was too comple or had nothing to do with the web afaik. Or are there better
solutions. I tried accessing the Server vaiables and the server enviroment
but that is useless.

Anything that Java can detect on the clientside (and I doubt
it could do what you want, certainly not without a signed
applet, or a Java application) can be overcome by a bit of
hacking. Java is not a solution to this problem.

You didn't give the type of thread (and it is anyhow not on-topic in
this group), so just a general hint: There are block lists out there
which might work for you.

No, the term "proxy" is used for a lot of different things in networking
and computer technology. Java can't help you here at all.

So, since this is not Java related, you might ask in a computer-security
related group. Or hire a security consultant, talk to your ISP, etc.

If you talk to these people, make sure you provide some more information
than just what you gave us (e.g. type of attack).
