title: How can I allow my site to be embeded within iframe?
body: <p>I have a site hosted on an external server and I would like to be able run it (within an iframe) from my local dev environment (localhost). Unfortunately, I am getting "This content cannot be displayed in a frame" message within the frame content when trying to load the page with the iframe. How can I resolve this?</p>
  
  <p>The local website that uses the iframe is classic asp, while the site hosted on an external server is MVC4. I only get the error when trying to iframe the MVC4 web app. When I try to iframe a classic asp site that sits on the same server (same domain) as the MVC4 app, I get no error.</p>
