I have the actionLogin and create cookie like here :

```
public function actionLogin()
    {
        $this->layout = 'login';

        $model=new LoginForm;

        if(isset($_POST['LoginForm']))
        {           
            $model->attributes=$_POST['LoginForm'];
            if($model->validate() && $model->login()){          
                $cookie = new CHttpCookie('loginSuccess',$model->username);
                $cookie->expire = 604800;                   
                Yii::app()->request->cookies['loginSuccess'] = $cookie;         
                $this->redirect('/ktbeauty/index.php/categories/index');
            }           
        }

        $this->render('login',array(
            'model'=>$model,
        ));
    }

```

And Now I have some controllers which must check to login before access controllers, if not login, it must redirect to login page, how can I work for this ?

thankyou very much
