Actually, while I've never done one, there are solutions around to
monitor the progress on the server side, and post back to another
location - probably a frame or asynchronous javascript.


In order to interface with Apache, you need to work on a fairly low
level, so that probably requires a high degree of familiarity with the
Apache/Interchange interface. You could also run the upload 'service' as
a separate mod_perl (or Catalyst, or whatever suits you) application
that works in conjunction with your Interchange process.

Anyhow, it's still no simple thing, and not something that is made easy
by the design of current web browsers.
