Create a new library file called MY_Controller:
class Administrator extends Controller
*/
{    
    function Administrator()
    {
        parent::Controller();
 
        // Protect the admin area, etc

/*
Then for your admin controllers you extend the Administrator class instead of the Controller.  That way you have common administrative logic in one place.
