An information processing device and an information processing method are provided which can provide services to all clients (users) at a certain service level while preventing a server from being overloaded by reducing concentration of access from some clients without requiring special processing on the client side. The server monitors requests sent from clients and does not execute business logic as an error when receiving intervals of requests do not exceed a threshold. Also, timing of a request being resent from a client next time is controlled by controlling return timing when an error response is returned to the client.
