title: iFrame content doesn't show in IE8
body: <p>I have a site with an iFrame.</p>
  
  <p>The host page has some very basic JS on it, the iframed page has simple JS too.</p>
  
  <p>When I embed the iframe as usualy: <code>&lt;iframe src="iframeURL" width="900" height="1000"&gt;&lt;/iframe&gt;</code> it works fine in all browsers but IE8.</p>
  
  <p>I tried various things:</p>
  
  <ul>
  <li>first: disabling all JS</li>
  <li>removing src attribute and adding it with JS</li>
  <li>using <code>&lt;object&gt;</code> instead</li>
  <li>I used proxy.php to make the content appear as if it were coming from the same domain</li>
  </ul>
  
  <p>It doesn't work in IE8 regardless what I do.</p>
  
  <p>The funny thing is that I can open the page I want to iframe in a separate tab and works just fine.</p>
  
  <p>If I change the src attribute to "some_other_random_page_from_internet" it works.</p>
  
  <p>The other thing is that both host and iframe use postMessage to communicate and I can see the communication is working OK, it's just the content which doesn't show, but when I inspect the page source with developers tools I can see the content is there.</p>
  
  <p>Is it possible that the content of the iframe causes issues? It's a basic HTML + basic JS, with JS disabled it shouldn't be an issue.</p>
  
  <p>Any ideas what else I could check?</p>
  
  <p>PS. I can't show the code (NDA , etc)</p>
