Class ResponseCache

java.lang.Object
java.net.ResponseCache

public abstract class ResponseCache extends Object
Represents implementations of URLConnection caches. An instance of such a class can be registered with the system by doing ResponseCache.setDefault(ResponseCache), and the system will call this object in order to:
  • store resource data which has been retrieved from an external source into the cache
  • try to fetch a requested resource that may have been stored in the cache
The ResponseCache implementation decides which resources should be cached, and for how long they should be cached. If a request resource cannot be retrieved from the cache, then the protocol handlers will fetch the resource from its original location. The settings for URLConnection#useCaches controls whether the protocol is allowed to use a cached response. For more information on HTTP caching, see RFC 2616: Hypertext Transfer Protocol -- HTTP/1.1
