分组下静态缓存问题

分组下的，静态缓存，怎么写啊？

Home,Admin两分组
静态缓存设置：
<?php
return array(
'Home:Index:index'=>array('{:action}','900'),
'Home:Index:message'=>array('{:action}','2000'),
'Home:Index:intrduce'=>array('{:action}','2000'),
'Home:Index:zhuanjia'=>array('{:action}','2000'),
'Home:Zixun:zixun'=>array('{:module}/{zid}','2000'),
'Home:Girl:view'=>array('{:module}/{uid}','1000'),
);
?>
