Proxy server check.

[djdaz]

Is it possible to check if someone is connecting to a website from a proxy server?

Im helping make a game and this is causing real problems.

Thanks in advance

You can check if the $_SERVER['HTTP_X_FORWARDED_FOR'] variable is set (that means the connection is from proxy). If it's not set, you can't tell whether it's proxy or non-proxy connection.
