Package org.apache.http.impl.client.cache.memcached

This package contains a storage backend based on memcached that can be plugged into a CachingHttpClient and used for storing cache entries.

Description

Interface Summary

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.
MemcachedCacheEntry	Provides for serialization and deserialization of higher-level HttpCacheEntry objects into byte arrays suitable for storage in memcached.
MemcachedCacheEntryFactory	Creates MemcachedCacheEntry instances that can be used for serializing and deserializing HttpCacheEntry instances for storage in memcached.

Class Summary

MemcachedCacheEntryFactoryImpl	Default implementation of MemcachedCacheEntryFactory.
MemcachedCacheEntryImpl	Default implementation of MemcachedCacheEntry.
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

MemcachedKeyHashingException	Indicates a problem encountered when trying to map a logical "storage key" to a "cache key" suitable for use with memcached.
MemcachedSerializationException	Raised when there is a problem serializing or deserializing cache entries into a byte representation suitable for memcached storage.
