Abstract
In a client-cache-server system, the weight value of a first object which is maintained in the cache and linked to a second object maintained in the server is determined. Based on the weight value, a decision is made as to whether prefetching is necessary. If the decision indicates that prefetching is necessary, the second object is prefetched from the server to refresh the cache. A further decision is made as to whether update enquiry is necessary based on the weight value. If the further decision indicates that update enquiry is necessary, a message is sent to the server for inquiring whether the first object has been updated in the server. If the server responds with a reply that indicates that the first object has been updated, the second object is prefetched from the server to refresh the cache.
