public class GatewayServer extends org.eclipse.jetty.server.Server
The Gateway server is a drop-in replacement for the default Jetty Server class for the Gateway receiving end - on the worker node.
  • It computes the HTTP dispatch port and sets it as system property jetty.http.port. It is crucial that the HTTP connector refers to this property in the configuration (as is default).
  • Any Gateway request from the dispatching side, the home process, will be responded with an appendix indicating session id and remaining TTL. This is used to update the worker lease, in case the worker node is detached
