Logoff problem

[Nilesh Patel]

When i have logout from my jsp page and after press "BACK" button of browser it is display my old page but i want to display login page

So user can't see previous page after logout ....

i have used session and write session.invalidate() for logff.

Session really only exists on the server - when you push the "Back" button the web browser pulls the page out of the local cache. You'll need to use something to prevent the page from being cached locally like -

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

i have tried but it is not working at my locale server but not working on hosting server...

hosting server is tomcat apache and jdk1.3

Do a "View HTML source" on the page you are getting from your host server and see if the line is included. They may be placing your page into some kind of template or something that has a conflicting directive. Or they may do some kind of caching on their end that doesn't honor this directive, or they may filter things like this out of pages - no caching means higher bandwith usage on the hosting server.

I have checked web page source code from my server its including all metatag

likes ..

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="0">
<META HTTP-EQUIV="Cache-control" CONTENT="no-store">
<META HTTP-EQUIV="Cache-control" CONTENT="max-age=0">
