Subject: [ebxml-msg] SynchReply module
All, Here is the proposal for the SyncReply module. Cheers, Chris X SyncReply Module There are use cases where it is necessary for the sender of a message, using a synchronous communications protocol, such as HTTP, to receive the associated response message over the same connection that the request message was delivered. In the case of HTTP, the sender of the HTTP request message containing an ebXML message needs to have the response ebXML message delivered to it on the corresponding HTTP response message. In the case where there are intermediary nodes (either ebXML MSH nodes or possibly other SOAP nodes) involved in the message path, it is necessary to provide some means by which the sender of a message can indicate that it is expecting a response so that the intermediary nodes can keep the connection open. The SyncReply ebXML SOAP extension element is provided for this purpose. X.1 SyncReply element The SyncReply element MAY be present as a direct child descendant of the SOAP Header element. It has the following attributes: - SOAP actor attribute with a value of "http://schemas.xmlsoap.org/soap/actor/next" - SOAP mustUnderstand attribute with a value of '1' or 'true' If present, this element indicates to the receiving SOAP or ebXML MSH node that the connection over which the message was received SHOULD be kept open in expectation that a response message will be returned via that same connection.
