Integration Server uses message addressing endpoint aliases to send responses to endpoints other than the one which initiated or sent the request. That is, when WS-Addressing is enabled and the request SOAP message contains a non-anonymous ReplyTo or FaultTo endpoints, Integration Server uses the message addressing endpoint alias to determine the authentication details to be used to send response to the ReplyTo and FaultTo endpoints.

When you define an endpoint alias for a provider or consumer web service descriptor, you can specify message addressing properties, which provides addressing information relating to the delivery of a message to a web service. This includes the destination address of a message or fault and the authentication credentials required to send a response to a different address than the one from which request was received.

For more information about creating a message addressing endpoint alias or specifying message addressing properties for a provider or consumer web service descriptor, see the section Creating an Endpoint Alias for Message Addressing for Use with JMS in the webMethods Integration Server Administrator’s Guide.
