ABSTRACT:
Embodiments disclosed herein provide a cache management system comprising a cache and a cache manager that can poll cached assets at different frequencies based on their relative activity status and independent of other applications. In one embodiment, the cache manager may maintain one or more lists, each corresponding to a polling layer associated with a particular polling schedule or frequency. Cached assets may be added to or removed from a list or they may be promoted or demoted to a different list, thereby changing their polling frequency. By polling less active files at a lower frequency than more active files, significant system resources can be saved, thereby increasing overall system speed and performance. Additionally, because a cache manager according to embodiments disclosed herein does not require detailed contextual information about the files that it is managing, such a cache manager can be easily implemented with any cache.
