org.apache.hc.client5.http.cache

Caching APIs for both the classic and the asynchronous HTTP transports.

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.
