Abstract
A switch device has an object ID rewrite unit and a file access control unit. The object ID rewrite unit, when an original object ID is contained in a reply to be transferred, rewrites the original object ID to an information entraining object ID by inserting server identification information into the original object ID, while when the information entraining object ID is contained in a reply to be transferred, restores the information entraining object ID to the original object ID. The file access control unit includes a table for managing a combination of address information of a server and server identification information, estimating address information of a server corresponding to server identification information contained in an information entraining object of a request to be transferred with reference to the table, and determines a destination of the request on the basis of the address information.
