title: Can I read a contents at iframe by using HTML5?
body: <p><a href="http://mydomain.com" rel="nofollow">http://mydomain.com</a></p>
  
  <pre><code>&lt;iframe src="http://otherdomain.com" frameborder="0" width="100%"&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>but I caught the message from my Chrome.
  Domains, protocols and ports must match.</p>
  
  <p>Does anyone who can resolve it?</p>
