PROBLEM TO BE SOLVED: To provide a service provider apparatus configured to enable smooth cooperation between specific web services, while ensuring security, a program, and a service providing method.SOLUTION: A service provider apparatus includes an association section, acquisition means, specifying means, determination means, and transmission means. The acquisition means acquires a resource request transmitted from a terminal device accessing a first service client. The specifying means specifies transfer destination information corresponding to authentication information included in the resource request and associated with the authentication information stored in the association section, from the association section. The determination means determines whether domain information included in the resource request and the transfer destination information coincide with each other in at least some domain layers. When they are coincident, the transmission means transmits a first response including information on the necessity of authentication and the domain information, to the terminal device. When they are not coincident, a second response including no domain information is transmitted to the terminal device.SELECTED DRAWING: Figure 6 |
