1. Backend:

(2) implementation:
We can get the file handler from cherrypy's embedded scheme,
and use it to read and write to a local file, ref:

The only thing we need to concern at backend is the file size,
cherrypy demo has proposed a example leverage cgi lib:

'file', or we construct formdata in ajax(for IE only supported in IE10+):

3. To support the progress bar in UI, we can utilize resumable js:

About the progress bar, we need to store it on backend to make this info
available to all users.
I think we can use the same approach to upload/download.
