This object turns the Distributed Director's sorting cache on or off, a cache that stores previous server-selection decisions to avoid recomputing metrics for repeat queries. Enabling the cache reduces CPU load and response latency for repeat DNS or HTTP queries from the same clients, but at the cost of potentially returning a stale best-server decision if server health or load conditions changed since the cache entry was created. An admin running a Distributed Director under heavy query load would enable this cache to avoid recomputing metrics for every repeat request, accepting that a server marked down moments ago might still get chosen until the cache entry expires.
