Prevent displaying of previous pages after logout in php
<p>I an using session_cache_limiter ('private_no_expire, must-revalidate'); on each page to avoid "Web page has expired" issue, so that issue is resolved. But i am facing the problem with logout. When i clicked log out the page is redirect to index page but when i clicked browser back button it redirects me to previous page which should not happened. I checked out previous solutions but nothing works for me. Any help will be grateful.
Thanks</p>
