IP Address

[Anon]

Is there a way to identify the IP address of a web page from where the user comes from?

I wish to compare the originating web site with a list of authorized ones. If a match, allow access; if not, redirect to another location.

Thanks...

$REMOTE_ADDR server variable.

Be careful, if the user goes through a proxy, $REMOTE_ADDR will give the proxy's IP.
