24. Terms and Definitions

24.1 Neighbor

In Squid, neighbor usually means the same thing as peer. A neighbor cache is one that you have defined with the cache_host configuration option. Neighbor refers to either a parent or a sibling.

In Harvest 1.4, neighbor referred to what Squid calls a sibling. That is, Harvest had parents and neighbors. For backward compatability, the term neighbor is still accepted in some Squid configuration options.
