title: iframe cross origin policy in IE
body: <p>Which versions of IE throw an exception if we try to access the cross origin data ? </p>
  
  <p>IE doesn't throw exception if I call
  <code>$('iframe[name="iframe"]').contents().find('body')</code> in my javascript code</p>
  
  <p>However, chrome and firefox do</p>
  
  <p><code>DOMException: Failed to read the 'contentDocument' property from 'HTMLIFrameElement': Blocked a frame with origin "http://localhost:8080" from accessing a cross-origin frame.(…)</code></p>
