Re: Removed session but Browser can still display the page

[Peter Maas]

When a client pushes the browsers 'back' button, this page is often read 
from cache... adding the following line to the HTML head might help:

   <META HTTP-EQUIV="Pragma" CONTENT="no-cache">

Hi,

I have a problem with using HttpSession class. When the user login, I 
create a new session by "request.getSession(true)". When the user 
logout, the session is removed by "session.invalidate()". In doing 
this, when the user is trying to go back to the previous page without 
login, the browser should not show the page because the servlet knows 
that the session for this user has already been invalidated. 

My problem is that In JBuilder, the code works as expected. But in 
Tomcat, it always failed. The browser can display the previous page 
when I use "Back" button in the toolbar, or when I type in the URL 
for the pages that should be displayed only after the user login. Can 
anybody help me?

Thanks in advance.

Kelly
