Abstract
The present invention provides techniques for allowing a server system to reduce the amount of communications and perform efficient operations. A server system returns an event message in response to an HTTP request including an application identifier from a client terminal. The server system comprises a first through a fourth server, where the first server receives the HTTP request from the client device and transfers the HTTP request to a plurality of installed second servers, the third server transmits a server identifier of the second server, to which the HTTP request has been transferred, to the fourth server after the HTTP request has been made, and the fourth server transmits an application identifier included in the HTTP request and an event message to the second transmission server indicated by the server identifier, and the second server suspends the HTTP request transferred from the request reception server, and transmits the HTTP request to the client device when it receives the event message from the fourth server.
