In order for the order management system to respond to the School of Fine Art's book request, routing information for the response is required. While this information could also be exchanged out of band, the headers transmitted in the original request message are typically used.

Lines 0204 The URI provided in the ReplyTo/Address element is used as the To/Address element in the response message. This information is used to route the response to either the original sender or an alternate endpoint.

If the SOAP processor encounters an error, a Fault is returned to the sender instead of the expected response message. These error messages can be directed to a different service that is specifically used to handle processing errors. The address for this message is provided in the request's FaultTo header element.
