Abstract

Objects are cached in a system adapted to receive requests for said objects from one or more clients. The system has at least one of a plurality of nodes. Each node of the plurality of nodes includes at least one of a plurality of caches. One or more performance criteria of the system are selected. At least one of a plurality of metrics is assigned to a selected performance criterion. The desirability of storing an object of the objects in any one of the plurality of caches is calculated by assigning at least one of a plurality of desirability values to at least one of the objects based on the at least one of the plurality metrics. Any one of the objects stored in the at least one of the plurality of caches is replaced based on the at least one of the plurality of desirability values.
