Abstract: PROBLEM TO BE SOLVED: To provide a device for responding to a request from an off-line client by generating a response based on the received request and stored plural requests and responses, and returning the generated response to the client as a response from a server. SOLUTION: When a client 92 is in an on-line state, a network traffic re- director 701 does not change network transmission between the client 92 and a sever 88. The client 92 transmits a request through a network connection 814 to the server 88, and the server 88 which receives this request executes a corresponding task, and returns a response through the network connection 814 to the client 92. When the client 92 is in an off-line state, the network traffic re-director 701 re-directs the request from the client 92 to an off-line server 702 in a local machine, and the off-line server 702 responds to this.
