Re: How does MakeConnection interact with request-response exchanges?

Jonathan,
  I would suggest you bring this up on the RX mailing lists - either on 
the public comment list or on the real mailing list - but I suspect the 
WSA WG isn't really the right spot for it.  :-)

How does MakeConnection interact with request-response exchanges?






I?ve been puzzling through the spaghetti of dependant specs for a while, 
and haven?t determined conclusively how to reconcile the WSDL in Appendix 
B with the MakeConnection example in Appendix C.6.
 
The WSDL describes request-response operations such as CreateSequence, 
with input CreateSequence and output CreateSequenceResponse messages. 
While the WSDL doesn?t describe a binding for this, it is easy to imagine 
a straightforward way to bind this to a SOAP/HTTP request-response.
 
However, the MakeConnection example shows a MakeConnection message 
resulting in a CreateSequence response message, which then results in a 
CreateSequenceResponse messages, followed by an HTTP 202.  That is, the 
first request corresponds to a one-way message (no problem here), the 
first response corresponds to a request of a request-response, and the 
second request corresponds to the response of a request-response.
 
What standard binding could be used to describe this behavior?  I can?t 
find any of the specs (WSDL 1.1, WSDL 2.0, WS-I BP) that explicitly say 
the WSDL-described request message must be mapped to an HTTP request, but 
I?m also not aware of any implementation that allows requests to be mapped 
to anything else.  Is this just a too-obvious-to-state loophole or am I 
missing something?
