The Routing Rule Step (REST)
The Routing Rule step is required. You can choose one of the following protocols in your Routing Rule step for routing the requests:
Straight Through routing (to route requests directly to the native service endpoint).
Context-Based routing (to route specific types of messages to specific endpoints according to context-based routing rules).
Content-Based routing (to route specific types of messages to specific endpoints based on specific values that appear in the request message).
Load Balancing routing (to distribute requests among multiple endpoints).
