<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE, NO-STORE, must-revalidate"> <META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE"> <META HTTP-EQUIV="EXPIRES" CONTENT=0>

its a solution that prevents caching we can't wipe the cache for what they already loaded. You should look it too prevent back button after logout page

You need to check if cookie is present in every page with only member access.Do the following if you havent:

1->check if cookie exists

2->if exists show info page

3->doesnt exist redirect to http://localhost/bss/bss/

Just redirect if there's no login $_SESSION, for example:

//on your protected pages
session_start();
if(!$_SESSION['logged']) {
    header("location:login.php");
}

<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">
<META HTTP-EQUIV="EXPIRES" CONTENT=0>

(If you are not using templates) Put this in your html pages

you need to clear browser cache by using these lines in all pages

header("Expires: Thu, 19 Nov 1981 08:52:00 GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
