I have been trying to kill a session, but it remains alive, a true Rasputin.
The code is below. The output
Killing session with ID: 944330779233294525
Dead session id: 944330779233294525
shows that the session has not died.
Can anyone help?
Thanks.

throws ServletException, IOException

HttpSession session = req.getSession(true);
String lgn = (String) session.getValue("username");
String pwd = (String) session.getValue("password");
ServletOutputStream out = res.getOutputStream();
res.setContentType("text/html");

Integer ival = (Integer) session.getValue("sessiontest.counter");
