3.1.4 Higher-Layer Triggered Events

Administrative actions starting or stopping the requestor IP/STS or relying party services, or changing service configuration data do not trigger protocol message exchanges. Protocol request messages are triggered by user action via a web browser requestor.

The wsignin1.0 request message is triggered when a web browser requestor sends an HTTP GET to a WS resource at a WS resource that requires users to be authenticated using this protocol.

The wsignout1.0 request message is triggered when a user explicitly requests to initiate the sign-out operation at a WS resource.

The wsignoutcleanup1.0 request message is triggered when a user explicitly requests to initiate the sign-out operation at a requestor IP/STS, or in response to the wsignout1.0 message discussed earlier.
