title: After update to MVC 5, iframe no longer works
body: <p>I updated my project MVC version to 5 and now iFrame does not load, I get this error: </p>
  
  <p><strong>Load denied by X-Frame-Options: www.blahblah.com does not permit cross-origin framing.</strong></p>
  
  <p>I noticed that for some reason now the X-Frame-Options header has SAMEORIGIN filled which does not allow the iframe to load a page from a different domain. This is a problem for me as I develop both the containing and inheriting page. I tried everything in IIS to change this header to no avail.</p>
  
  <p>Anyone encountered this yet?</p>
