Is there a way to determine whether net traffic has come directly or through High Secure Proxy ? I am using IP detection by http://show-ip.net http://ip.needthe.net http://whatismyipaddress.atspace.com http://myip.atspace.org http://showip.atspace.org And WHOIS server at http://whois.show-ip.net

First of all, what's your setup like? Internet >> router >> proxy device >> LAN or Internet proxy >> router >> LAN or something completely different? Not knowing how you're setup makes it nearly impossible to answer your question.

You are right - my info was not sufficient. Problem is this: user can access www server 1) directly, then $remoteaddr = $_SERVER['REMOTE_ADDR']; - client real address 2) via transparent proxy server - it can be deteted if HTTP_X_FORWARDED_FOR is set, then $ipaddr = $_SERVER['HTTP_X_FORWARDED_FOR']; - client address 3) via anonymous proxy - it can be detected if (isset($_SERVER['HTTP_VIA']), then $ipaddr = $_SERVER['HTTP_VIA'] - proxy address; 4) via high anonymity (elite proxy) - HTTP Servers of this type does not send HTTP_X_FORWARDED_FOR, HTTP_VIA and HTTP_PROXY_CONNECTION variables. Server doesn't even know you are using proxy server an of course it doesn't know your IP address. As you see - impossible to distinguish between 1) and 4) and I can't know if user address $_SERVER['REMOTE_ADDR'] is his real IP or elite proxy IP. Im seeking way to separate cases 1 add 4, may be some JScript code or something like this.

Well, I'm a network technician, not a JScripter so your code doesn't mean much to me. Without an idea of your setup and whether or not the proxy is internal or external I won't be able to give you any help whatsoever, sorry.
