How will you know if it completed correctly?
I mean, what about the incoming file will tell you that it's "complete"?
I'm not sure how the _server_ will be able to tell the difference between a complete and incomplete submission.
hmm - as I say, not sure.
Actually I'm not terribly sure you have to do anything. Off the top of my head I'd say that if the user gets a page back then it completed. If not, then probably not.
