Web Response Cache

This feature enables local caching for web responses. It includes the distributedMap feature and performs automatic caching of web application responses to improve response times and throughput. Applications can include a cache-spec.xml file to customize the response caching. The cache may be distributed through addition of a network cache provider such as WebSphere eXtreme Scale.
