This class is a storage backend for cache entries that uses the - * popular Ehcache cache implementation. - * In particular, this backend allows for spillover to disk, where the - * cache can be effectively larger than memory, and cached responses are - * paged into and out of memory from disk as needed.

- * - *

N.B. Since the Ehcache is configured ahead of time with a - * maximum number of cache entries, this effectively ignores the - * {@link CacheConfig#getMaxCacheEntries()} maximum cache entries} - * specified by a provided {@link CacheConfig}.

- * - *

Please refer to the - * Ehcache documentation for details on how to configure the Ehcache - * itself.
