 * This technique works even better in situations where a stale response is better than no response.
 * To permit stale cached responses, use the `max-stale` directive with the maximum staleness in
 * seconds:

 * ```java
 * Request request = new Request.Builder()
 *     .cacheControl(new CacheControl.Builder()

   * implementation; otherwise refreshes will be performed during unrelated cache read and write
   * operations.

   * <p>Currently automatic refreshes are performed when the first stale request for an entry
   * occurs. The request triggering refresh will make a synchronous call to {@link
   * CacheLoader#reload}
   * to obtain a future of the new value. If the returned future is already complete, it is returned

everywhere. Otherwise the two cache instances will stomp on each other, corrupt the response cache, and possibly crash your program.

Response caching uses HTTP headers for all configuration. You can add request headers like `Cache-Control: max-stale=3600` and OkHttp's cache will honor them. Your webserver configures how long responses are cached with its own response headers, like `Cache-Control: max-age=9600`. There are cache headers to force a cached response, force a network response, or force...

- Whenever a pod was successfully bound to a node, the kube-apiserver  cleared the pod's `nominatedNodeName` field. This prevented stale information from affecting external scheduling components.
