public class RoutingSlip extends org.apache.camel.support.AsyncProcessorSupport implements org.apache.camel.Traceable, org.apache.camel.spi.IdAware, org.apache.camel.spi.RouteIdAware
Implements a Routing Slip pattern where the list of actual endpoints to send a message exchange to are dependent on the value of a message header.

This implementation mirrors the logic from the Pipeline in the async variation as the failover load balancer is a specialized pipeline. So the trick is to keep doing the same as the pipeline to ensure it works the same and the async routing engine is flawless.
