title: Is it possible to use iframe with localhost address in source ?
body: <p>My HTML markup is pretty simple</p>
  
  <pre><code>....
  &lt;iframe width="800" height="800" src="http://localhost:69345/Handler.ashx"/&gt;
  ...
  </code></pre>
  
  <p>but this page is blocked by all browser that I've used.
  I'm wondering is there any workaround for this issue?
  Surely, I completely understand that in case when my page will be deployed in production there will be no problems. However, <strong>how can I do any testing if iframe is blocked on local?</strong></p>
  
  <p>Thank you in advanced</p>
