Configuring remote request dispatcher caching
The creation and handling of the remote request dispatcher (RRD) message and the transfer of this data across a network creates substantial overhead. To improve performance, the local machine can receive the cache rules of the remote server and know when to cache the response locally to prevent the RRD call altogether.
