Abstract: PROBLEM TO BE SOLVED: To provide a push base filtering system in a client-server hierarchy and a method for annexing the annotation of meta information related to the contents of a push object or urgency or both of them to the object based on using state information. SOLUTION: Objects are staged in a server so that each filtered object can be quickly accessed at the time of requiring it thereafter. A contents provider or an upper level proxy for annotating an object transmits information including urgency, a summary or a title, group classification, or push discrimination, or all of them by using a PICS protocol so that using state or preference information related to the pushed object including using state information and user preference based on object group classification is transmitted to an upper level in hierarchy and each staged object is transmitted to a lower level in the hierarchy, improving the efficiency of caching.
