Session Management problem in Struts

[patriot indian]

I am facing a peculiar problem....I am having an application in which there are 2 different types of users...each shown a different page after logging in...I am chacking at each page whther a user has logged in and if he is not logged in am redirecting him to login page...But the problem is Suppose one user logs in and after sometime he is logging out...Now second user logs in...On pressing back button he is redirected to the pages of the other user and he can do all the stuffs..How to prevent him from accessing that data...

Disable caching.

1) session.invalidate();
2) disable catch
