Any endpoint of the FIM Service Service may return, in any one of its responses, a header element that it uses to keep track of the state of a session. The object type that stores this information is the Context type, referred to as the context header. The following XML Schema defines the structure of the context header.

If a response from the FIM Service includes a context header, the client should add the same context header to any subsequent requests to the service.
