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

This package contains a cache module that can be used for HTTP/1.1 client-side caching. The primary classes in this package are the CachingHttpClient, which is a drop-in replacement for a DefaultHttpClient that adds caching, and the CacheConfig class that can be used for configuring it.

Interface Summary

Interface	Description
FailureCache	Increase and reset the number of errors associated with a specific identifier.
HttpCache
SchedulingStrategy	Specifies when revalidation requests are scheduled.

Class Summary

Class	Description
AsynchronousValidationRequest	Class used to represent an asynchronous revalidation event, such as with "stale-while-revalidate"
AsynchronousValidator	Class used for asynchronous revalidations to be used when the "stale- while-revalidate" directive is present
BasicHttpCache
BasicHttpCacheStorage	Basic HttpCacheStorage implementation backed by an instance of LinkedHashMap.
BasicIdGenerator	Should produce reasonably unique tokens.
CacheableRequestPolicy	Determines if an HttpRequest is allowed to be served from the cache.
CacheConfig	Java Beans-style configuration for a CachingHttpClient.
CacheConfig.Builder
CachedHttpResponseGenerator	Rebuilds an HttpResponse from a net.sf.ehcache.CacheEntry
CachedResponseSuitabilityChecker	Determines whether a given HttpCacheEntry is suitable to be used as a response for a given HttpRequest.
CacheEntity
CacheEntryUpdater	Update a HttpCacheEntry with new or updated information based on the latest 304 status response from the Server.
CacheInvalidator	Given a particular HttpRequest, flush any cache entries that this request would invalidate.
CacheKeyGenerator
CacheMap
CacheValidityPolicy
CachingExec	Request executor in the request execution chain that is responsible for transparent client-side caching.
CachingHttpClient	Deprecated. (4.3) use CachingHttpClientBuilder or CachingHttpClients.
CachingHttpClient.AsynchronousValidationRequest
CachingHttpClient.AsynchronousValidator
CachingHttpClientBuilder	Builder for CloseableHttpClient instances capable of client-side caching.
CachingHttpClients	Factory methods for CloseableHttpClient instances capable of client-side caching.
CombinedEntity
ConditionalRequestBuilder
DefaultFailureCache	Implements a bounded failure cache.
DefaultHttpCacheEntrySerializer	HttpCacheEntrySerializer implementation that uses the default (native) serialization.
DefaultHttpCacheEntrySerializer.RestrictedObjectInputStream
ExponentialBackOffSchedulingStrategy	An implementation that backs off exponentially based on the number of consecutive failed attempts stored in the AsynchronousValidationRequest.
FailureCacheValue	The error count with a creation timestamp and its associated key.
FileResource	Cache resource backed by a file.
FileResourceFactory	Generates Resource instances whose body is stored in a temporary file.
HeapResource	Cache resource backed by a byte array on the heap.
HeapResourceFactory	Generates Resource instances stored entirely in heap.
ImmediateSchedulingStrategy	Immediately schedules any incoming validation request.
IOUtils
ManagedHttpCacheStorage	HttpCacheStorage implementation capable of deallocating resources associated with the cache entries.
OptionsHttp11Response
Proxies	Proxies for HTTP message objects.
RequestProtocolCompliance
ResourceReference
ResponseCachingPolicy	Determines if an HttpResponse can be cached.
ResponseProtocolCompliance
ResponseProxyHandler	A proxy class that can enhance an arbitrary HttpResponse with Closeable.close() method.
SizeLimitedResponseReader
Variant	Records a set of information describing a cached variant.
WarningValue	This class provides for parsing and understanding Warning headers.
