I have a requirement in which the user should not be able to see the books in the site unless he is logged in. And the user is not able to see the content.
The problem is when a user logs in, views a book and its child pages, and logs out; he is still able to view the pages he opened before when he was logged in, by pressing the back button of the browser. He is not able to make any changes though.
This may create problems when users visit the site from a public computer, log off, and go away without closing the browser window.
Is there a module or any setting change I can use to solve this issue?
