document.referrer isn't providing the original page url?

Question

My script is running in an iframe in an iframe and I'm trying to get the root referrer (the url the iframe is on). It's not working. Here's the code:

<script type="text/javascript">
    var referrer_url = document.referrer;
    document.write("You come from this url: " +referrer_url);
</script>

Any ideas?

What do you mean by, "It's not working?" Do you get the wrong answer? Is it null? An error? vvv whoa good one :-) — Pointy, Jul 23 '12 at 11:43

Document.referrer doesn't get set on all occasions.

You should use window.top.location.href.toString(); but it requires that they both are on the same domain.
