Zend Framework: Documentation Zend_Cache_Frontend_Page
Zend_Cache_Frontend_Pageはとても便利だと思います。実際に使ってみたところ少しハマってしまいましたので参考になればと思います。

・知らぬ間にクッキーがあった。
→make_id_with_cookie_variablesをtrueに。

GoogleAnalyticsなどで意図しないCookieが埋め込まれている場合がありますので、その場合はCookieがあってもキャッシュされるようにしなくてはいけません。

・start()後にob_gzhandlerを使用している。
キャッシュ開始($cache->start())後にob_gzhandlerがあると、復元できない状態でキャッシュされてしまうようです。ob_gzhandlerを使いたい場合は、キャッシュをスタートさせる前にob_gzhandlerを宣言しましょう。

他にもハマリどころはありますでしょうか?
私もまだまだ使い始めですので、また何かあればUPしていこうと思います。

一応ソースを載せておきます。といっても公式そのままですが。

‘^/article/’ => array(‘cache’ => false), // ArticleController はキャッシュしません
‘^/article/view/’ => array( // ……が、ArticleController の “view” アクションは

$backendOptions = array(
‘cache_dir’ => ‘/tmp/’
