That tells you if the connection to your machine was broken.  It
doesn't tell you if the user downloaded the file completely and it is
now saved on their disk.

Are you sure there isn't a proxy sucking up the file and closing the
connection before the download completes?

Not sure what the plan is but a proxy might throw on a Vary header and
trigger this: http://support.microsoft.com/?kbid=824847

I think the safe bet is to allow the download over some period of time
-- or maybe even ask the user "Click here if you received the file"
kind of thing.
