If you enter an invalid video id in YouTube (e.g. ) 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 "") in javascript?

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

You are looking for document.referrer.

Use a <meta> tag in your codebase with these two attributes name and content, i.e.:

<meta name="referrer" content="always" />

This is how you can set the referrer value after a redirect.
