Web :: General :: locating client IP in JavaScript

I want to know about a method for detecting client's IP which is
running behind a proxy server.
Is there any possible way in Javascript to get the IP address of the
client's machine which is using proxy.

Well, it's indeed not possible to directly get the IP adress of the client behind the proxy, but i think it is possible to use (nasty) cookies on the client machine to store its IP as any other information (session variable, visit count, etc) so you can retrieve it anytime. If cookies are activated in the client browser, of course.

Personally, I think this is the only solution. The server only sees the proxy's IP@ so it can't help.
