Backgroundrb devel - Feb 2007 - [Slightly OT] Timing out during File Save

Apologies in advance for the slightly OT post, and for the cross-post, but I
thought you folks would probably have more experience with this
''problem'' given your use of BackgroundRb.

A little background (no pun intended ;-) )
I''m using BackgroundRb for session management.  After a set period of
user inactivity I kill their session and all the information they''ve
entered and files created from that info is deleted.  I know it''s a bit
unusual but it''s warrented in this app.  BackgroundRb was the tool I
needed because I need to display a count-down timer in their browser.  It is
working beautifully.

The ''problem'' I''m trying to solve is that the
''Save File'' dialog box is modal so it prevents the timer in
the browser from getting updated.  The file download to the client has finished,
so the timer on the server is reset and BackgroundRb starts counting down again.
But the visitor has no way of knowing that.  It looks to them like the timer has
stopped but, in fact, the count down has restarted and is underway.  Their
session may time out and data get deleted before they finish the File Save on
their PC.  At that point they''re left looking at a browser that still
says they have time left but that''s, in fact, completely done and
unresponsive.

Ideally, I''d like not to restart the timer until I know
they''ve finished the ''Save File'' on the client. 
Anybody have any ideas on how to do this?  Or any other ideas on how I might
handle it other than just warning them before they start the
''Save''?

Thanks,
Bill
