title: Why session.invalidate doesn't work in IE browser?
body: <p>I implemented a sevlet filter in my application, and within the filter, if I find some specific url pattern, I will use request.getSession().invalidate() to logout and clear the session, then redirect to a login page.</p>
  
  <pre><code>session.invalidate();
  session.setAttribute("hi", true);
  response.sendRedirect("login.jsp");
  </code></pre>
  
  <p>but I found, after that I enter username and password, then submit the login form, the previous session seems not be completely cleared.</p>
  
  <p>So is it possible to let me completely clear out the session and just like start a new IE instance ?(BTY, my code works in FF and Chrome).</p>
