I am trying to write an application with the help of jsdk2.0\javawebserver2.0 and i
want to track the session.
What I am trying to do is that there is a paid web site that allows users
to enter the site after allocating him a certain time.He cannot surf beyond that time
limit.So far so good .I can track the session but my requirment is that if the user
closes his browser before the allocated time or the internet connection at his end
fails then I have to calculate the total time surfed by him and accordingly update his
account.
So how do i come to know that browser has been closed or the connection at users end
has failed.I tried to write a thread that checks every minute
if(session==null) System.out.println("logged out");but it does not work.
How can the servlet or server come to know when the browser has been closed.
Kindly help urgently as my student project hangs on it
Many thanks in advance.may contact at [EMAIL PROTECTED]
