An unknown request occurs in the following situations:
  • When there is an active conversation
  • When there is not an active conversation
    If there is not an active conversation, a request is identified as unknown if there are no stateless transactions that can satisfy the request. In this case, the service image response for unknown stateless requests becomes the reply.
If a request cannot be matched to a follow-on transaction:
  • If the navigation tolerance is not Close, the conversation starter transactions are given the chance to satisfy the request.
  • If the request is still unmatched and a stateless transaction can produce a reply, then that is sent. The current session continues to remember where it is in its conversational tree.
If that fails, the service image response for unknown conversational requests becomes the reply.
