+go-cache is an generic in-memory key:value store/cache similar to memcached that is
 suitable for applications running on a single machine. Its major advantage is
 that, being essentially a thread-safe `map[string]interface{}` with expiration
 times, it doesn't need to serialize or transmit its contents over the network.
