Interface Summary

Interface	Description
HttpAsyncCacheInvalidator	Given a particular HTTP request / response pair, flush any cache entries that this exchange would invalidate.
HttpAsyncCacheStorage	HttpAsyncCacheStorage represents an abstract HTTP cache storage backend that can then be plugged into the asynchronous (non-blocking ) request execution pipeline.
HttpCacheCASOperation	Atomic Compare-And-Swap (CAS) cache operation.
HttpCacheEntrySerializer<T>	Serializer / deserializer for HttpCacheStorageEntry entries.
HttpCacheInvalidator	Given a particular HTTP request / response pair, flush any cache entries that this exchange would invalidate.
HttpCacheStorage	HttpCacheStorage represents an abstract HTTP cache storage backend that can then be plugged into the classic (blocking) request execution pipeline.
ResourceFactory	Generates Resource instances for handling cached HTTP response bodies.

Class Summary

Class	Description
HeaderConstants	Records static constants for various HTTP header names.
HttpAsyncCacheStorageAdaptor	HttpAsyncCacheStorage implementation that emulates asynchronous behavior using an instance of classic HttpCacheStorage.
HttpCacheContext	Adaptor class that provides convenience type safe setters and getters for caching HttpContext attributes.
HttpCacheEntry	Structure used to store an HttpResponse in a cache.
HttpCacheStorageEntry	This class contains a HttpCacheEntry along with its key.
Resource	Represents a disposable system resource used for handling cached response bodies.

Enum Summary

Enum	Description
CacheResponseStatus	This enumeration represents the various ways a response can be generated by the caching HttpClient; if a request is executed with an HttpCacheContext then a parameter with one of these values will be registered in the context under the key HttpCacheContext.CACHE_RESPONSE_STATUS.

Exception Summary

Exception	Description
HttpCacheUpdateException	Signals that HttpCacheStorage encountered an error performing an update operation.
ResourceIOException	Signals a generic resource I/O error.
