-  module Cache
-    # A cache store implementation which stores data in Memcached:
-    # http://www.danga.com/memcached/
-    #
-    # This is currently the most popular cache store for production websites.
-    #
-    # Special features:
-    # - Clustering and load balancing. One can specify multiple memcached servers,
-    #   and MemCacheStore will load balance between all available servers. If a
-    #   server goes down, then MemCacheStore will ignore it until it goes back
-    #   online.
-    # - Time-based expiry support. See #write and the +:expires_in+ option.
-    # - Per-request in memory cache for all communication with the MemCache server(s).

-      # addresses. Each address is either a host name, or a host-with-port string
-      # in the form of "host_name:port". For example:
-      #
-      #   ActiveSupport::Cache::MemCacheStore.new("localhost", "server-downstairs.localnetwork:8229")
