<p><P>PROBLEM TO BE SOLVED: To call a service inside a firewall from an external Web application without changing settings on the firewall. <P>SOLUTION: Relay servers are prepared on both sides of the firewall. A request is first output from the internal relay server to the external relay server, to be on standby for a request from a server which provides a Web service outside the firewall. When the external relay server receives a service request to the inside from the server outside the firewall, it is transmitted to the internal relay server as a response to the request, to allow the Web service to be called beyond the firewall. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
