Abstract: A system and method is provided wherein, in one aspect, a currently-requested item of information is stored in a cache based on whether it has been previously requested and, if so, the time of the previous request. If the item has not been previously requested, it may not be stored in the cache. If the subject item has been previously requested, it may or may not be cached based on a comparison of durations, namely (1) the duration of time between the current request and the previous request for the subject item and (2) for each other item in the cache, the duration of time between the current request and the previous request for the other item. If the duration associated with the subject item is less than the duration of another item in the cache, the subject item may be stored in the cache.
