Keeping State After Submitting

A sample demonstrating how to keep the uploaded file state across page posts. Upload a few files, submit the form, and the list survives the round trip.

Live demo

Try it: upload a file, press Submit Form, and note that the file list and the clock both update while the state is kept.
