The server needs an "if" in order to avoid sending TXN-NAME when it receives VTXN-NAME (and not sending TXN-NAME is the main reason for this change). If the server doesn't send VTXN-NAME then the response is not complete and the server is relying on the the proxy to make it complete. I think it is better if the server generates a complete response. -- Philip
