How to get the top URL from a Facebook application?

How can I get the top URL (Facebook\'s address) in my iframe application?

Is there a good solution on that?

Answer 1

If you can wait for first load, you can use jQuery:

$(document).ready(function()
{
    var myurl = window.location.pathname;
    $.get("test.php", { url: myurl } );
});
