The browser then sends another HTTP GET request (to the URL from the meta refresh) back to Geeklog (which then triggers the second part of the plugin upgrade). The referrer would have to be sent with that GET request, i.e. the browser would have to create it.

Perhaps I'm missing something, but the 'header("Location: $url");' call
does send a referer. It's the referer that it itself received, it merely
copies it over. And since we go from plugins.php to plugins.php and once
more to plugins.php, I'm guessing it could be good enough. Try the
example in the attached tarball by clicking the link on page1.php

Could this work or am I just embarrassing myself further on the list?
