Yii2 如何做多页的分页缓存 [ 2.0 版本 ]

public function behaviors()
{
    return [
        [
            'class' => 'yii\filters\PageCache',
            'only' => ['index'],
            'duration' => 60,
            'variations' => [
                \Yii::$app->language,
            ],
            'dependency' => [
                'class' => 'yii\caching\DbDependency',
                'sql' => 'SELECT COUNT(*) FROM post',
            ],
        ],
    ];
}

这样好像只是一个页面的缓存，如果是多页的这种怎么做呢
