You're going to have to wait for a response doing this. That's just how
http works. Request->Response. However...

If you're willing to take a little risk that the files are somehow wrong
and don't need to tell the user this immediately, you can make the wait
for response be very short. That is, may the php program that handles
the request (accepts the files), save them, and then fork off a new
process to actually do something to them. The child process, however
cannot ever communicate back to the user directly -- it'll have to
notify them by other means, like email. See

http://www.php.net/manual/en/pcntl.example.php

for how to start a process that detaches itself from the parent.
