`$ENV{REMOTE_ADDR}` (IP address) and `$ENV{REMOTE_HOST}` (domain name or undefined), as documented in the CGI spec. `remote_host` is CGI's interface to this data.	[reply] [d/l] [select]

Failed? You mean you got the proxy's address? Well, that's to be expected since the proxy IS the client of the server. There's no way of knowing more than that from HTTP. You might be able to do more using JavaScript since that will run in the browser, not on the server.	[reply]
