droonga/express-droonga at ab2834c [master] Split cache and middlewares that use cache (Groonga-commit) - Groonga - fulltext search engine.

cacheのインスタンスを作ってそれを明示的にミドルウェアに渡す、というつく 
りは、cache関係のモジュールの内部の都合が外に染み出ている感じがして、よ 
くないのではないかと思いました。

          var cache = new droonga.cache({
            size: cache
          });
          application.use('/cache/statistics',
                          cache.statistics);
          application.use(cache.middleware({
            rules: [
              {
                regex: /^\//,
                ttlInMilliSeconds: 1000
              }
            ]
          }));

という感じで初期化するスタイルの方がいいと自分は思うのですが、どうでしょ 
うか。
