title: open my website in iframe or modal pop up instead of redirecting to my page
body: <p>Currently I have a controller that returns a view, so to integrate with my website the other website has to post the form to my above mentioned controller that returns the view. </p>
  
  <p>Now what I want is to provide some script to one who wants to integrate with my website, such that on posting form to my controller they dont redirect to my page, rather my webpage opens on their page itself in a modal popup or an iframe.</p>
