如何在http和www之间共享用户认证登录数据

当用户打开网站www.dominname.com时，我正在使用Yii框架和登录到该站点时，上的身份验证或用户会话数据不相同http://dominname.com所以用户在打开HTTP时必须再次登录，我如何才能在WWW和HTTP上进行身份验证登录，或者在WWW与HTTP之间共享会话数据。Yii有什么配置可以解决这个问题吗？

如果用户检查rememberMe，此代码对我有效，否则用户将不会登录有人知道怎么解决这个问题吗？

1. 主/配置

     'user' => array(
       // enable cookie-based authentication
       'class' => 'WebUser',
       'allowAutoLogin' => true,
   ),
   'session' => array(
   'savePath' => dirname(__FILE__) . DIRECTORY_SEPARATOR . '../../session',
   'cookieMode' => 'allow',
       'cookieParams' => array(
           'path' => '/',
           'domain' => '.domainname.org',
           'httpOnly' => true,
       ),
   ),
   

2. 组件/WebUser

   class WebUser extends CWebUser {
     public $identityCookie = array(
    'path' => '/',
    'domain' => '.domainname.org',
     );
    public function init() {
    $conf = Yii::app()->session->cookieParams;
    $this->identityCookie = array(
       'path' => $conf['path'],
       'domain' => $conf['domain'],
    );
    parent::init();
    }
     public function logout($destroySession = true) {
     if ($this->allowAutoLogin && isset($this->identityCookie['domain'])) {
        $cookies = Yii::app()->getRequest()->getCookies();
         if (null !== ($cookie = $cookies[$this->getStateKeyPrefix()])) {
            $originalCookie = new CHttpCookie($cookie->name, $cookie->value);
             $cookie->domain = $this->identityCookie['domain'];
            $cookies->remove($this->getStateKeyPrefix());
            $cookies->add($originalCookie->name, $originalCookie);
            }
      }
     parent::logout($destroySession);
     }
    }
