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.
