Miss,
Two ways of finding out.
First ...every user has a Session Object. The time of survival for
this object is set by the Web Administrator. Default value is 30 minutes.
After 30 minutes, the user's Session Object is reclaimed by the JVM for
memory. User's session object becomes 'null' then.
Second....whenever the user exits out of the web-browser, the session
object is automatically made null.
So if you encounter a 'null' session object then it is a safe bet that the
user has logged out/timed out .
Hope this helps.
Amar..
