note 102463 added to reserved.variables.server

An alternative way to pudding06 at gmail dot com's suggestion to prohibit non-local visitors.

<?php
($_SERVER['REMOTE_ADDR'] === $_SERVER['SERVER_ADDR']) or die(header($_SERVER["SERVER_PROTOCOL"]." 404 Not Found"));
?>

Rather than testing against 127.0.0.1, checks that the REMOTE_ADDR and the SERVER_ADDR are equal.  Thus, the check will pass regardless of the IP address used in the request, but it will still restrict non-local visitors (who will be sent a 404).
