The client knows whether it's been authenticated, it will get back a PAOS
message with a well-defined content type that can't mean anything else. If
that comes back, then the original request has to be resubmitted once
authentication is done and a session is in place.
All of that should be easily hidden inside an HTTP library or a wrapper
around one. If you can't buffer the data, then the library should signal
that somehow, because the same problem would exist with HTTP
authentication (you'd get a 401 challenge and the original request would
have been lost).
