[narendrafl]

Hai
   In my flex application i need to log every action performed by user. but 
problem is when user closes the browser i nedd to log that also(means user 
loggedout like that in my DB). can anybody give suggetions about it. The 
solution must work independent of the browser.

Thanks in advance who tries to answer my prob.
