A client apparatus requests a server apparatus to transmit information. The server apparatus receives the request from the client apparatus, and determines whether a state of an information source satisfies a predetermined condition. The server apparatus, as a result of the determination, if the state of the information source does not satisfy the predetermined condition, suspends a response to the client apparatus, while, if the state of the information source satisfies the predetermined condition, acquires information corresponding to the request from the information source as a response to the client apparatus, and transmits the acquired information to the client apparatus.
