getSession() returns a session regardless of there's apre-
existing session.Since we always get back an HttpSession
instance back from the method,the only way to know if the
session is new is to ask the session itself:

HttpSession session=request.getsession();

if(Session.isNew())
{
out.println("A NEW SESSION");
}
else
{
out.println("WelCOme Back");
}
