See "man lookupd" and the section on cache agents, specificly: CacheAgent The operation and configuration of the cache agent are described in detail in the sections above. The configuration options for the Cache agent are ValidateCache, CacheCapacity, and TimeToLive. These options may be set globally and/or for specific categories. Options set for a spe- cific category will over-ride the global setting. Note that CacheAgent should always appear first in a LookupOrder specifi- cation to allow lookupd to find cached entries before searching other information services. ...and... NILAgent The NILAgent always returns a result for a query, so it stops any search. However, it returns a negative record, which carries the meaning that the item requested does not exist. The use of negative entries in a cache is controversial, so lookupd does not include the NILAgent in its default lookup order. [ ... ] -- -Chuck
