When you use REMOTE_ADDR for getting the IP of the current user,
sometimes you get the IP of the ISP Cache server.
When this happens, the HTTP_X_FORWARDED_FOR is also set, it
contains the IP of the user.
So with this script, you always get the right IP:
if (getenv(HTTP_X_FORWARDED_FOR)){
$ip=getenv(HTTP_X_FORWARDED_FOR);
}
else {
$ip=getenv(REMOTE_ADDR);
}
