[Yii Framework] Share the session with memcache in Yii

When developing distributed applications with Yii, naturally, we will face that we have to 

share the session in different machine. So here we will use memcache to do it. 

here is the example to store the session with memcache in Yii, in the main.php file: 

         'cache'=> array(
            'class'=>'system.caching.CMemCache',
            'servers'=> array(
                 array(
                    'host'=>'192.168.1.1',
                    'port'=>11211,
                ),
            ),
         ),
         'sessionCache'=> array(
            'class'=>'system.caching.CMemCache',
            'servers'=> array(
                 array(
                    'host'=>'192.168.1.2',
                    'port'=>11211,
                ),
            ),
        ),
        'session' =>  array (
            'class'=> 'CCacheHttpSession',
            'autoStart' =>  true,
            'cacheID' => 'sessionCache',  // we only use the sessionCache to store the session
            'cookieMode' => 'only',
            'timeout' => 1400
        ),

For the details, pls refer to http://www.yiiframework.com/doc/api/1.1/CCacheHttpSession#cacheID-detail
 

Have fun with Yii!
