I have made an authentication system. When i try to logout, and press back button, or try to login with other account, it always get back to the first refreshed page. i have used cookies, and clear cookies when logging out.

app.get('/logout', (req, res) => {
    if (req.session.user && req.cookies.user_sid) {
        res.clearCookie('user_sid');
        res.redirect('/');
    } else {
        res.redirect('/login');
    }
});

what should i add to clear caches after log out ???? and thank you.
