Answer 1

I think that you must search not only for HTTP_X_FORWARDED_FOR, but for all that, depent what your loading ballance using

Context.Request.ServerVariables[CheckAllBelowList]

"HTTP_X_COMING_FROM",
"HTTP_X_FORWARDED_FOR",
"HTTP_X_FORWARDED",
"HTTP_VIA",
"HTTP_COMING_FROM",
"HTTP_FORWARDED_FOR",
"HTTP_FORWARDED",
"HTTP_FROM",
"HTTP_PROXY_CONNECTION",
"HTTP_CLIENT_IP",
"CLIENT_IP",
"FORWARDED",

The return of one of that, is the actual Ip of you client, except if is other proxy, I also need to learn how some one can get this, to find the user that is behind 2-3 proxy's...

If you know any other, please tell me so.
