Using the back button after logging out shows you pages from the authenticated user's session.
I found a solution for this, need to set the header like this to fix this issue-
drupal_add_http_header('Cache-Control', 'no-cache, no-store, max-age=0, must-revalidate, post-check=0, pre-check=0');
But the problem where i need to set this header?
I set the header in
index.php file. After that i am not able to see any other pages while i am logged in. (getting page not found error)
Any solution, how to fix this issue??
