This invention makes it possible to, in a pull transfer communication protocol, to interrupt forwarding of information on the server side at a timing desired by a user. To achieve this, a client includes a first request unit for transmitting a content request to the server and the server includes a first response unit for transmitting content requested from the first request unit to the client. The client further includes a second request unit for requesting the server to make a response if a predetermined status has occurred, and the server further includes a second response unit for deferring, if the request made by the second request unit is received, a response if the predetermined status has not occurred, and transmitting the response to the client if the predetermined status has occurred.
