title: How could I hide the url of a site within an iframe?
body: <p>I have a site that has an iframe linking to another site with the following example iframe code:</p>
  
  <pre><code> &lt;html&gt;
   &lt;body&gt;
  
   &lt;iframe src="http://google.com" width="100%" height="600"&gt;
  
   &lt;/iframe&gt;
  
   &lt;/body&gt;
   &lt;/html&gt;
  </code></pre>
  
  <p>So, for the above example, how could I prevent visitors from finding the url: <a href="http://google.com" rel="nofollow">http://google.com</a> ?</p>
