<p>A client transmits Event::Subscribe('DSI_CHANGED') to a server. The server returns an event number preset for the 'DSI_CHANGED' event. After obtaining the event number, the client transmits Event::notify to the server and requests a certain notification of occurrence of an event including a 'DSI_CHANGED'. When the DSI of the received carousel is changed, namely, a 'DSI_CHANGED' event occurs at a certain timing after the reception of the Event::notify, the server transmits the event number corresponding to the 'DSI_CHANGED' event to the client in response to the Event::notify. For the period from the time when the server notifies the client of the occurrence of the event number till the time when the client transmits Session::detach to the server, the contents of the carousel before the event number occurs is used continually.</p> |
