Re: Log out problem

Thu, 06 Mar 2003 13:55:03 -0800

Hi,

In order to not cache the information, I set the following HTTP headers:

 response.setHeader("Cache-Control", "no-cache,no-store,must-revalidate");
 response.setHeader("Pragma", "no-cache");

I set these headers at the beginning of my doPost() method. Still the same thing is happening. When I click the back button on my browser, I get the previous page in the session instead of the login page.

After a user logs out and clicks the "back" button, I want him to login again to access the site.

Is there something I am doing wrong?

Thanks for any help in advance!

Sincerely,

--Andy.

As Victor says you could stop the jsp from being cached especially if  the jsp performs some process which you dont want to accidentally repeat. But also the JSP will create a new session by default unless you specify otherwise. You can check for a new session (session.isNew()) or alternatively set the jsp not to create a session (<%@ page session="false"%>) then check that a session exists.
