How to get referrer URL after a redirect in javascript
<p>If you enter an invalid video id in YouTube (e.g. <a href="http://www.youtube.com/watch?v=XXX" rel="nofollow">http://www.youtube.com/watch?v=XXX</a>) it will redirect you to a page saying it is a malformed video ID. Is there a way to get the original URL (in this example "http://www.youtube.com/watch?v=XXX") in javascript?</p>

<p>(I'm talking about Javascript that will run on the browser after the redirect, through Firebug)</p>
