> As Andrew Kondratev has pointed out on https://github.com/apache/wicket/pull/255, we can use FormData to send multipart data via Ajax. This makes the current iframe workaround obsolete.
> Advantages:
> - real Ajax !!1!!!
> - we can drop a lot of code in wicket-ajax-jquery.js
> - users can use Wicket.Ajax to send files as extra parameters, as requested in pull request #255
> FormData is supported in Edge and IE 10. I'm not sure whether we still support older browsers, but as fallback users can
> - continue using Wicket 7 (supported for the next years)
> - switch to non-Ajax uploads
> - use a polyfill for FormData (several available on github)
