缓存 js 输出

我的 elsewhere 页面通过加载 friendfeed 的 js 文件展现了我在互联网上的足迹，包括我在 twitter 上的信息、在 del.icio.us 上收藏的书签等。但这个 js 文件的输出内容比较大，以至于每次浏览 elsewhere 页面都会出现短暂的停顿，所以我将其进行了缓存，每1小时更新一次，以减少浏览的不良体验。

<?php
$num = 40;
$uri = 'http://friendfeed.com/embed/widget/centeur?v=2&num='.$num.'&hide_logo=1&hide_comments_likes=1&hide_subscribe=1&width=515';
if (!$output = wp_cache_get('friendfeed', 'js_cache')){
if (!class_exists('Snoopy')) include_once(ABSPATH . WPINC . '/class-snoopy.php');
$snoopy = new Snoopy;
$snoopy->fetch($uri);
$output = $snoopy->results;
wp_cache_add('friendfeed', $output, 'js_cache', 3600);
}
?>

<script type="text/javascript"><?php echo $output; ?></script>
