logout method in laravel 5

I'm trying to apply a logout in my laravel 5.5 project with this method:

Route::get('/logout', function () {

        Auth::logout();

        return redirect('login');
    })->name('auth_logout'); 

But when I click on the back of the browser, it returns me to the previous page it was in and the user is still authenticated when the session should have been deleted.

I have created a middleware to deal with this:

public function handle($request, Closure $next)
    {
        header('Last-Modified:'.gmdate('D, d M Y H:i:s').'GMT');
        header('Cache-Control: no-store, no-cache, must-revalidate');
        header('Cache-Control: post-check=0, pre-check=0',false);
        header('Pragma: no-cache');

        return $next($request);
    }

This middleware works for me; but I feel that this method is not effective at all because if we click several times in the back there comes a time when it returns to the previous page and the user remains authenticated.

There will be some way to delete the session in laravel when I run the logout() to automatically redirect to the login. Reviewing the method logout() of Auth this is empty.
