Keeping track of users

Hi,
I'm quite new to struts and I'm sure there would be a common solution to 
this question.
Is there a standard way to keep track of users logged onto the web 
application? If there is, how to you handle the situation where they've 
simply closed the browser (perhaps this causes an event - I don't know), 
where their PC has crashed, or even if they've logged into the 
application multiple times (assuming this is allowed in business logic).
Any help is appreciated.
Thanks
J.

 From what I gather, the only way to tell immediately is to have had a 
request made and to have an exception be thrown when you try to send 
data to the output stream.  I'm not sure exactly how it works - I am not 
that concerned with measuring such things.  You could, using the session 
binding techniques another poster described, and some sort of attribute 
of the bean you're binding, manage for the bean to know whether it is 
being removed because of a timeout, or because you have explicitly said 
for it to be removed.  Then, knowing what your server uses as a timeout 
(I'm sure there's some way to get this, though I don't know how 
personally) you could subtract that amount of time from the duration of 
their logon to get a closer approximation of how long their session was 
valid.

HTH,

Eddie
