Memcached based caching backend implementation.

See: Description

Interface Summary

Interface	Description
KeyHashingScheme	Since the HttpCacheStorage interface expects to use variant-annotated URLs for its storage keys, but Memcached has a maximum key size, we need to support mapping storage keys to cache keys.

Class Summary

Class	Description
MemcachedHttpAsyncCacheStorage	This class is a storage backend that uses an external memcached for storing cached origin responses.
MemcachedHttpCacheStorage	This class is a storage backend that uses an external memcached for storing cached origin responses.
PrefixKeyHashingScheme	This is a KeyHashingScheme decorator that simply adds a known prefix to the results of another KeyHashingScheme.
SHA256KeyHashingScheme	This is a KeyHashingScheme based on the SHA-256 algorithm.

Exception Summary

Exception	Description
MemcachedKeyHashingException	Signals a problem encountered when trying to map a logical "storage key" to a "cache key" suitable for use with memcached.
MemcachedOperationCancellationException	Signals memcached operation cancellation.
MemcachedOperationTimeoutException	Signals memcached operation timeout.
