title: Certain sites are not loading in iFrame
body: <p>I trying to open certain sites in iframe but my browser is not loading those sites. My Source code is</p>
  
  <pre><code>&lt;html&gt;
    &lt;body&gt;
      &lt;iframe src="http://www.microsoft.com"&gt;
        &lt;p&gt; Your browser does not support iframes. &lt;/p&gt;
      &lt;/iframe&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>This snippet is working fine and it loads microsoft.com in iFrame but when I change src to <a href="http://www.amazon.com" rel="nofollow">http://www.amazon.com</a> it does not load amazon.com in iFrame. I am not sure why it is happening and is there any solution available for that.</p>
  
  <p>Regards,
  Alex</p>
