Key information is retained in a load balancer. Encrypted server identification information, which is encrypted with the key information, is included in an HTTP request which the load balancer receives. The encrypted server identification information is included in a response message from a real server to a client terminal and in a reissued HTTP request. The server identification information is decoded with the key information when the load balancer receives the reissued HTTP request, and access to the specified real server is achieved. Thus, while ensuring security even with a different routing load balancer, an HTTP request to a specified real server is possible. |
