ActiveSupport::Cache::MemCacheStore

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).
