I think the only way to get anywhere then is to build yourself a test
case and see if it is at all reproducible. In particular, whether the
bug lies in NSURLDownload or NSURLConnection (or maybe even
WebDownload).

In the cases where I see this occur I'd say that the time from start
to first resume attempt is less than 30 minutes. I do not believe it
could be related to session timeouts. Secondly, in my mind it's a
bug if the application simply refuses to continue. Often what you
see is if it cannot continue / resume it will start again. I'm not
seeing that I'm seeing it literally go no where when it sees that it
cannot resume and only if I go out of your way to delete the file
will it make any form of progress by starting again.

So, I often see this same behavior in Safari, iTunes etc whereby
when it's downloading something and you try to resume. It simply
will not resume or will say timeout _until_ you remove the file and
start again. In iTunes the progress bar simply will not show any
more progress until the previous partially downloaded file is
removed. I've seen this in Software Update as well where you'll
have to go in it's cache to delete partially downloaded updates or
it will never resume from where it's left off.
The fact that I see these across so many apps tells me its possibly
a framework issue.
Anybody seen this behaviour on their machines?
I've seen it, but I wouldn't be so quick to assume it's a bug in
NSURL - resumed downloads requires a cooperative web server that
understands and responds appropriately to the HTTP Range: header.
Also, with ADC downloads for instance, your session key is part of
the URL, so if your session times out what you'll actually be
requesting is a different URL, not a resumed download of the same
URL.
I'm not saying it *isn't* a bug - just that there are other
possible explanations, and I haven't seen any evidence to support
one theory or another.
