In JEE6 there is support for asynchronous
servlets. This means that the servlet can be called asynchronously.
I am struggling to understand how the asynchronous servlet will work in practical scenario.
e.g
1. User A makes a servlet call using a url say http:/www.example.com/app/asyn
2. The servlet returns immediately while spawning a new
thread to process the servlet request
3. User A then moves to another screen
4. In the meanwhile the servlet processing finishes, then how would this response be sent to client.
If somebody can explain this it will be very helpful
