Empty $HTTP_REFERER variable

[Krzysztof Piotrowski]

Hi all,

I hale recently started using php - god fun :-D

I decided to make visits statistics.
My webpage http://www.kolumb.net/ has a statistic at

http://www.kolumb.net/mysql/list_stats.php

I hale a problem with $HTTP_REFERER variable ("Visited From" column).
Sometimes it seems empty, for no reason. Could anyone help??

The value of $HTTP_REFERER (or $_SERVER['HTTP_REFERER']) is not guaranteed
to be correct, because it is supplied by the browser. Norton
Internet Security for instance filters it out :-(
