Read IFrame cookie

Question

I created an iframe and I loaded a website in it ( i dont have access to this website - it wasnt written by me)

<script type="text/javascript">

  var el = document.createElement("iframe");
  el.setAttribute('id', 'ifrm');
  document.body.appendChild(el);
  el.setAttribute('src', 'http://AWEBSITE.com/');
  alert(document.getElement("iframe").cookie); //This doesnt work.....
</script>

Can I use javascript in some way to read my cookies of the iframe?

Solution

It is impossible because of the same origin policy. Do you really want someone to be able to stick an iframe on any page, point to any domain, and get your cookies?
