javascript - get parent.location.url - iframe - from child to parent

Question

I got a page that is displayed within an iframe.

I need to get the parent.location.url with js from that page (child page).

Both sites are in different domains.

I'm trying:

alert(parent.location.url)

But I get this error:

Permission denied for http://parentdomain to get property Location.URL from http://childdomain.

???? Is it possible?

var referrer = document.referrer;
alert(referrer);
