Loggin out from Form based authentication

Question

Using servlet 2.3 is there a way to log a user out when he has signed in using form authentication. I know servlet 3.0 has this feature of logging out. What should servlet 2.3 users do for logging out ?

Just invalidate the session.

request.getSession().invalidate();

Don't forget to send a redirect afterwards.

response.sendRedirect(request.getContextPath() + "/login.jsp");

Thanks for clearing that up. I was actually forwarding it and getting funny behavior. Redirection did the trick. – Murphy316 Jun 28 '12 at 03:39

Yes, the session is still in the current request, but not anymore in the next request. – BalusC Jun 28 '12 at 03:41

Look here Regarding Logout. It also explains the difference between

Servlet 3.0 HttpServletRequest.logout()

and

session.invalidate() method.
