All Implemented Interfaces:

jakarta.servlet.Servlet, jakarta.servlet.ServletConfig, Serializable

public class LongpollTransportServlet
extends AbstractTransportServlet<LongpollTransportServlet.LongpollSession>

The LongpollTransportServlet dispatches all incoming and/or outgoing messages using a longpoll mechanism. In addition to the longpoll mechanism that is able to send message batches, it emulates a full-duplex communication with the client, by holding a non-longpoll request open in order to push subsequently messages to the client.
