How do I close a connection when the session ends?

Question

I have a website that is using JavaMail to display a user's mail through the browser. I'd like to keep the connection to the mail server open during the whole session that the user is logged in, in order to improve response time. The problem is, I can't detect if a user closes their browser so that I can close the connection to the server.
Is there a way for me to close the mail server connection when the session ends?
Thanks.

Create session listener, Impliment sessionDestryoyed
method with your connection close statements.I was wondering how to use the listener for a Servlet as well, what would you type in that method to close the connection?.
public class ServletListener
     implements
          ServletContextListener,
          ServletContextAttributeListener,
          HttpSessionListener,
          HttpSessionAttributeListener
public void sessionDestroyed(HttpSessionEvent arg0)
          //System.out.println( arg0 );
}
