You could use the application server's session management - the user session 
will time out by default after a given amount of inactivity so you could 
probably hook in there.
 
If you need some kind of real-time logging then you might want to take a look 
at the Flash Comm Server - this way you could establish a persistent connection 
between client and server. If the browser is closed the connection to the Flash 
Comm Server will be closed and the Flash Comm Server in turns could send a 
Remoting request to your backend and inform it to write to the db.
 
One implication is that the Flash Comm Server uses the RTMP protocol which may 
not get through a restricted firewall. It's also possible to tunnel RTMP 
through HTTP but again, a packet filter could suppress this traffic.

Betreff: [flexcoders] Catching the Closing of the Browser in Flex


Hello all,
 
I wish to write to a database whenever a user logs out. When the browser is 
closed, this is an implicit logout: the user can click the close icon on the 
title bar, go to File-Exit in the browser's menu, press Alt-F4, browse to 
another page, etc. It would be nice to be able to catch when this happens, so 
as to write the log and logout the user.
 
I have tried using the unload event in the Application tag, but this does not 
seem to work.
 
Does anybody have any other ideas? Is there soemthing obvious I am missing?
 
Thanks a lot,
 
Barry.
