Patent ID: 8898313

Claim:
A relay device that relays communication between an information processing terminal and an information processing device, the relay device comprising: a first extraction unit that, when receiving from the information processing device response information for initial request information issued by the information processing terminal, extracts first session identification information for identifying a session established between the information processing terminal and the information processing device, and an address of the information processing device, from the received response information, and stores the extracted information and address in a first storage unit; a transmission unit that transmits the response information to the information processing terminal, and transmits session supporting address information including the extracted first session identification information and address of the information processing device to at least one of other relay devices; a second extraction unit that extracts second session identification information, from request information for a second time or later received from the information processing terminal; and a query unit that, when the session supporting address information corresponding to the extracted second session identification information is not stored in the first storage unit, queries the at least one of the other relay devices for the session supporting address information corresponding to the second session identification information.
