<p>When license information is transferred between a server machine (101) and a client machine (103), an identifier which is unique to a series of communication sequences is provided. Such identifier is sent when a communication is performed between such two machines as well as when the license information is updated. Therefore, when a message for transferring the license information is received by the use of the same identifier, a response message is returned without updating the license information.</p> |
