Abstract: A system and method for caching objects of non-uniform size. A caching logic includes a selection logic and an admission control logic. The admission control logic determines whether an object not currently in the cache is accessed may be cached at all. The admission control logic uses an auxiliary LRU stack which contains the identities and time stamps of the objects which have been recently accessed. Thus, the memory required is relatively small. The auxiliary cache serves as a dynamic popularity list and an object may be admitted to the cache if and only if it appears on the popularity list. The selection logic selects one or more of the objects in the cache which have to be purged when a new object enters the cache. The order of removal of the objects is prioritized based both on the size as well as the frequency of access of the object and may be adjusted by a time to obsolescence factor (TTO).
