You could try to create a listing of defined globals, something like
<?php
echo "<xmp>";
while (list($key, $value) = each($GLOBALS))
echo "$key => $value\n";
echo "</xmp>";
?>
and look how your webserver defines the HTTP_REFERER variable.
Anyway, there are situations where NO referer variable is available. That's
always the case when you get to the script not using a link, but type it
into the location bar directly (or call it up from your favorites).
AFAIK, IIS on NT4 sets HTTP_REFERER correctly if available.
