Odd behaviour with storage cookie.

[whisher]

Hi

I'm using a Storage_Cookie like http://metaversedeveloper.com/2009/01/03/logging-in-users-via-zend_auth-without-sessions-in-php-zend-framework/ I only add json_encode/decode to manage the not scalar data.

I've had trouble with the logout method because the $auth->hasIdentity() was still true after the logout action.

I end up with this code and it works but it seems to me just a little odd

public function clear()
    {
        if (!setcookie($this->_cookieName,
                       false, // clears the cookie
                       time()-$this->_expire,
                       $this->getBasedir())) {
            throw new Zend_Auth_Storage_Exception('Failed to clear cookie');
        }
        /* odd ! with a DEBUG session it is set with the user email !!!!!!!
used as identity
 */
        unset($_SESSION[$this->_cookieName]);
        unset($_COOKIE[$this->_cookieName]);
    }

In my bootstrap
protected function _initAuth()
    {
        $auth = Zend_Auth::getInstance(); 
        if(null !== W_Cookie::get('wh')){
            $auth->setStorage(new W_Auth_Storage_Cookie(md5('ayn'), md5('ayn')));
        }
        else{
            $auth->setStorage(new Zend_Auth_Storage_Session(md5('ayn')));
        }
        Zend_Registry::set('auth', $auth);
    }
In my controller
LOGIN
W_Cookie::deleteCookie('wh'); 
                    if(!empty($remember)){
                         W_Cookie::setCookie('wh',md5(time())); 
                         $this->auth->setStorage(new W_Auth_Storage_Cookie(md5('ayn'), md5('ayn')));
                    }
                    $this->auth->getStorage()->write($data);

LOGOUT
 W_Cookie::deleteCookie('wh'); 
        $this->auth->clearIdentity();
        $this->_helper->redirector('index','index','default');


Does anyone know why ?
Thanks in advance
Bye
