Ah, yes. It's there when the page is actually referred from somewhere,
otherwise it's not.
Thanks, Kevin.
Now my simple assignment becomes a conditional assignment to avoid clutter
in the error log:
if ( isset($_SERVER['HTTP_REFERER']) )
$glb_http_ref = $_SERVER['HTTP_REFERER'];
else
$glb_http_ref = "";
instead of
$glb_http_ref = $_SERVER['HTTP_REFERER'];
Learning as I go... :)
