Client "browser" cache
30.2. Client "Browser" Cache Resteasy has the ability to set up a client-side, browser-like, cache. You can use it with the Client Proxy Framework, or with raw ClientRequests. This cache looks for Cache-Control headers sent back with a server response. If the Cache-Control headers specify that the client is allowed to cache the response, Resteasy caches it within local memory. The cache obeys max-age requirements and will also automatically do HTTP 1.1 cache revalidation if either or both the Last-Modified and/or ETag headers are sent back with the original response. See the HTTP 1.1 specification for details on how Cache-Control or cache revalidation works.
