    Patent number: 6128701
    Abstract: The invention provides a system and system for automatically refreshing documents in a cache, so that each particular document is refreshed no more often and no less often than needed. For each document, the cache estimates a probability distribution of times for client requests for that document and a probability distribution of times for server changes to that document. Times for refresh are selected for each particular document in response to both the estimated probability distribution of times for client requests and the estimated probability distribution of times for server changes. The invention also provides a system and system for objectively estimating the value the cache is providing for the system including the cache.
