Abstract

Part of the functionality and information of a server is published to a client, and the client makes a request based on this information, and before embedding the request from the client into processing, a server determines whether the request is invalid. In addition, before the processing is executed into which the request from the client has been embedded, whether the request is invalid is determined again.

This configuration enables a detailed request from the client to be safely embedded into the server'"'"'s processing and also enables the server and system to be stably operated.
