    }
An {@link HttpService} that supports <a href="https://datatracker.ietf.org/doc/html/rfc6455">
The WebSocket Protocol</a>.
This service has a few different default values for {@link ServiceConfig} from a normal {@link HttpService}
because of the nature of WebSocket. See {@link WebSocketServiceBuilder} for more information.
