Such a proxy processes a single request sent by a client over unicast, and distributes the request to a group of servers, e.g., over UDP/IP multicast as the defined default transport protocol. Then, the proxy collects the individual responses from those servers and relays those responses back to the client, in a way that allows the client to distinguish the responses and their origin servers through embedded addressing information. This document updates RFC7252 with respect to caching of response messages at proxies.}, }
