<pre>The bug is related to latest Safari on Mac.
You can run the simplest test and see that it's Safari regression bug (as working fine on old Safari 5.1). It is always yours (Webkit/Apple dev team) decision to keep Safari buggy or to fix it.
The steps to reproduce the bug:
1. create HTML form with <input type=file>
2. on form post interact with JavaScript and send JavaScript FormData (as POST request) with Ajax to /validate-token
3. for /validate-token make server-side redirect to /upload-request
4 - now you will see that all headers and the posted data are cleared and not sent/redirected to /upload-request while expected.
It works fine (all data sent to /upload-request) on all browsers, except latest Safari (it might be a Safari bug for years).
