I suspect that these extensions would be out of scope for this module,
which seems to be more about making it easier to write your own form

That said, I'm sure no-one's going to stop you from coding.

If you used http basic authentication, the effect of this could come
for free. But you don't.

Fundamentally, what you seem to want is for the handler to read a part
of the POST request body and then decide whether to respond and close
the connection, or accept the rest of the request body.

I'm not sure how you'd go about that.

That one is probably better handled in your own form handler -- you can
be given the original suggested filename and the 10-digit filename, and
do a "mv" of one to the other, handling duplicates and evil filenames as
you see fit. No need to hard-code the handling within the module.

You probably will want to make sure that "upload_store" is on the same
filesystem as you wish the files to end up on.
