public class OSRegisterAppRequest

extends OSRequest

The OSRegisterAppRequest request registers the application with the ClientStage. An application must register with the ClientStage to receive an OSAppId before sending any other requests. The application identitifier must be included in all other requests to OceanStore. All results sent back to the application will include the application identifier of the requesting application allowing applications to filter results intended for them.

Because the registration request and result must be exchanged without the benefit of an application identifier, the request/result pair includes a nonce for uniqueness. The application wishing to register with the ClientStage should include a nonce in its registration request. That nonce will be included in the result to allow the registering application to determine if a result is in response to its request.
