the technique is not to link directly to that page, but to go through one more stop on your site before launching off
the normal page has a link like this
<a href="jumpto.php?href=http://php.net">link</a>
jumpto.php is on your site, it looks at $GET['url']
then logs it or does whatever to it...
then jumps to the page with a [man]header[/man]("Location: {$GET['url']}");
make sense?
