title: Postback of dropped content in HTML5
body: <p>We have an ASP.NET MVC3 web application. We generate HTML5 pages.</p>
  
  <p>And now, we would like the <code>dragged &amp; dropped</code> content (images, word documents...) into the <code>HTML5</code> page to be sent to the Web Server and then processed (content and MIME type) in C#.
  How can this be solved?</p>
