---------------------------------------------------------------------- (Y)et another (U)ni(C)ast invalidation server

It has a single parent cache. Whenever a page is updated in this server it informs the parent cache, which will in turn propagate the update (or invalidation) to the whole cache hierarchy. ----------------------------------------------------------------------
