defaultRouteAction property
defaultRouteAction takes effect when none of the pathRules or routeRules match.
The load balancer performs advanced routing actions, such as URL rewrites and header transformations, before forwarding the request to the selected backend. If defaultRouteAction specifies any weightedBackendServices, defaultService must not be set. Conversely if defaultService is set, defaultRouteAction cannot contain any weightedBackendServices. If defaultRouteAction is specified, don't set defaultUrlRedirect. If defaultRouteAction.weightedBackendServices is specified, don't set defaultService. URL maps for classic Application Load Balancers only support the urlRewrite action within a path matcher's defaultRouteAction.
Implementation
HttpRouteAction? defaultRouteAction;
