Abstract
A real-time information transmission system can immediately transmit information updated on a server to a client, even if directly communication between the server and the client is not established. If the server receives a page request from the client, the server returns a requested page to the client. The same connection ID is added to the request from the client and to an associated response from the server. The client analyzes the page. If an event request is included in the analyzed page, the client adds another connection ID to the request and sends it to the server. Using the connection ID, the server sends an event to the client each time the event has occurred. The client processes the event and reflects the processed result on a screen of a display.
