 === Combined Global Filter and GatewayFilter Ordering
 
-When a request comes in (and matches a Route) the Filtering Web Handler will add all instances of `GlobalFilter` and all route specific instances of `GatewayFilter` to a filter chain. This combined filter chain is sorted by the `org.springframework.core.Ordered` interface, which can be set by implementing the `getOrder()` method or by using the `@Order` annotation.
