## Uses of Interface
org.apache.http.client.cache.HttpCacheUpdateCallback

Packages that use HttpCacheUpdateCallback
org.apache.http.client.cache: This package consists largely of constants and interfaces that are necessary for building new storage backends for the `CachingHttpClient` or for those clients wanting to get a little more behavioral information out of the cache module (for example, whether a particular response was a cache hit or not).
org.apache.http.impl.client.cache: This package contains a cache module that can be used for HTTP/1.1 client-side caching.
org.apache.http.impl.client.cache.ehcache: This package contains a storage backend based on Ehcache that can be plugged into a `CachingHttpClient` and used for storing cache entries.
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.
