CakePHPのSecurity->blackHoleCallBackの設定の基本

public function beforeFilter(){
		$this->Security->blackHoleCallback = 'blackhole';
		parent::beforeFilter();
	}

public function blackhole($type){
		switch($type){
			case 'csrf' :
				$this->Session->setFlash(__('不正な送信が行われました'));
				$this->redirect(array('controller' => 'topics', 'action' => $this->action));
				break;
			default :
				$this->redirect(array('controller' => 'topics', 'action' => 'index'));
				break;
		}
	}
