Abstract
When license information is transferred between a server machine and a client machine, an identifier which is unique to a series of communication sequences is provided. The identifier is sent when a communication is performed between the 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.
