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.
