title: Fatal error: Call to undefined method CookieComponent::del()
body: <p>Hi to all 
  I have this strange error in my code.
  I want to make a cookie system with cakephp, and in app_controller.php I include</p>
  
  <p>var $components = array('Auth', 'Cookie');
  var $helpers = array('Html', 'Form', 'Session'); </p>
  
  <p>but everytime I click on Logout link the error appears.
  This is the function </p>
  
  <p>function logout() {
    $cookie = $this->Cookie->read('User');
      if($cookie)
       $this->Cookie->del('User');
    $this->Session->setFlash('Logout');
    $this->redirect($this->Auth->logout());
   }</p>
  
  <p>Where I can look for a solution?
  Thank you dude</p>
