Re: WS-Routing Reverse Message path - Http Explicit rev erse endpoints .

In the example you described, D will respond to C using a new HTTP request
rather than responding over the same socket that C used to send the request
to D. Since C used HTTP, a response is required and the WS-Routing spec
indicates that this response should be something like 200, 202, or 204
(preference is 202). D then processes the request and sends its response
back to C as an HTTP request. In this case the transport request/response
semantics do not align with the SOAP and WS-Routing request/response
semantics.

While C is waiting for the response from D, it must be holding on the
pending socket connected to B in order to send the response from D back to
B. The response from D will come in as a new HTTP request. C can optionally
make use of the vid attribute on the via element to help with the
association between the response from D and the socket back to B. Using the
vid attribute, C can lookup a cached reference to the socket to B. Without
the vid attribute, it will be trickier to associate the HTTP request from D
with the response to the socket back to B. Maybe using the relatesTo element
would be enough.

Subject: [SOAP-RP] WS-Routing Reverse Message path - Http Explicit reverse
endpoints .


Hi All,

How Can WS-Routing Reverse message explicit endpoints be supported?

Like I have A message which needs to traverse the forward and reverse
message paths to D and back to A A(Inital Sender)-->B(Intermediary 1)-->C
(Intermediary 2)-->D(Ultimate
Receiver)
All the parties use http endpoints.
Suppose C specifies an Explicit reverse Endpoint to D and B has specified
implicit reverse endpoint to C. Then B is expecting to receive the reverse
path message from C in response stream corresponding to the forward path
message's request stream. How will the C's reverse message path explicit
endpoint write to the Response stream corresponding to another
request(Request from B to C in the forward message path).

I hope i am not confusing.

Thanks in Advance.
