Introduction to One Request, a Mandatory Response, and an Optional Response

In this type of interaction, the client sends a single request to a service and receives one or two responses. Here, the request is to order a product online. If the product is delayed, the service sends a message letting the customer know. In any case, the service always sends a notification when the item ships. Figure 5-8 provides an overview.
