Php Craft CMS使Craft用户在多个环境之间保持日志记录

我正试图使一个多环境的网站与工艺CMS的每个环境是一种不同的语言。当点击不同的语言和不断变化的环境时，有没有办法让我的Craft用户保持登录状态。我有两个类似于craft/config/general.php的环境：

 'frenchSite' => array(
    'siteName' => 'French Site',
    'devMode' => true,
    'siteUrl' => array(
        'en' => 'http://website-en.com',
        'fr' => 'http://website-fr.com',
    ),
    'environmentVariables' => array(
        'basePath' => '/home/vagrant/Projects/WebSite/dev/public/',
        'baseUrl'  => 'http://website-fr.com/', 
    ),
    'googleAnalyticCode' => '',
    'mailchimp' => '',
    'StripeID' => '',
    'GoogleMap' => '',
),

'EnglishSite' => array(
    'siteName' => 'English Site',   
    'devMode' => true,
    //'defaultCookieDomain' => 'website-fr.com',
    'siteUrl' => array(
        'en' => 'http://website-en.com',
        'fr' => 'http://website-fr.com',
    ),
    'environmentVariables' => array(
        'basePath' => '/home/vagrant/Projects/WebSite/dev/public/',
        'baseUrl'  => 'http://website-en.com/', 
    ),
    'googleAnalyticCode' => '',
    'mailchimp' => '',
    'StripeID' => '',
    'GoogleMap' => '',
),
