Abstract: PROBLEM TO BE SOLVED: To automatically distribute the important information by deciding repetitively the state of a client entity until the client entity is set in a prescribed operating state and transmitting the decided state of the client entity to a source entity. SOLUTION: If an input requests a state notification, an awareness handler is called out and an awareness server 1010 reads the ID of a requester and the ID of a target client. A local pointer shifts to a 1st entry of a request buffer and checks the state of the target client. Then the local pointer decides whether or not the target client is set in its desired state and sends a notification to the requester. The important information such as the number of a port where an application of a Web browser, etc., which receives the push request of a target client entity is carried out is returned in the notification. A push proxy server 1040 reads the returned important information and uses it.

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.
