Re: Tricky question - referrer from ousite, or from intern?

$_SERVER['HTTP_REFERRER'] (or is it $_ENV['HTTP_REFERRER']?) is your only option. Unfortunately it's not guaranteed to be set by the browser, so your current method of accepting and tracking referrers is flawed, sorry. A page.php?aid=xxxxx entry point, combined with sessions or cookies to keep track of the affiliate ID is a proven method of making things work.
