Method and apparatus for processing a request using proxy servers
First Claim
1. A request processing method of processing a request requesting task processing in a computer system,the computer system having a client computer for transmitting the request requesting task processing, a plurality of application servers for processing the request, a proxy server for receiving the request and transmitting the request to the plurality of application servers, and a session management server for managing the request,the proxy server having a first interface, a first processor coupled to the first interface, and a first memory coupled to the first processor,the plurality of application servers each having a second interface, a second processor coupled to the second interface, and a second memory coupled to the second processor,the request processing method comprising steps of:
- producing, by the proxy server, at least one duplicate request from an original request transmitted from the client computer, and transmitting the first request which is one of duplicate and original requests to each of the plurality of application servers;
transmitting, by the plurality of application servers, a result of processing of the first requests to the proxy server;
notifying, by the plurality of application servers, the session management server of session information including identifiers of the plurality of application servers and identifiers of the first requests;
determining, by the proxy server, a result of the processing used for responding to the client computer upon receiving the result of the processing of the first requests;
notifying, by the proxy server, the session management server of the identifiers of the plurality of application servers which have transmitted the determined processing result and an identifier of the request transmitted from the client computer;
accessing, by the plurality of application servers, an external server storing data used for the task processing; and
stopping, by the proxy server, processing for the first requests other than a first request for which the processing for update data stored in the external server has been completed first, when the original request transmitted from the client computer includes a request for updating data stored in the external server.

Abstract
Provided is a request processing method of processing a request requesting task processing in a computer system including the steps of: transmitting, by a proxy server, a first requests which is one of duplicate and original requests to application servers; transmitting, by the application servers, a result of processing of the first requests to the proxy server; notifying, by the application servers, a session management server of session information including identifiers of the application servers and identifiers of the first requests; determining, by the proxy server, a result of the processing used for responding to a client computer upon receiving the result of the processing of the first requests; and notifying, by the proxy server, the session management server of the identifiers of the application servers which have transmitted the determined processing result and an identifier of the request transmitted from the client computer.
