A single service level REQUEST PIPELINE in a stage might optionally branch out into operational pipelines (at most one PER operation, and optionally a default operational pipeline). The operation is determined by user-selected criteria. The response processing starts with the relevant operation pipeline which then merges into a single service-level response pipeline. The following FIGURE shows an example of operation pipelines in a proxy service.

For one-way operations, the response pipeline is executed with an empty message. This permits a response to be constructed for the proxy service, enabling bridging between request/response and one-way operations. The bridging MECHANISM means that proxy service input can be one-way while its output is request/response or vice versa. The proxy service either absorbs the response from the invoked service or generates one for the client. Actions in the response flow may also be used to do post processing on the message after it has been routed to the business service or the proxy service.
