All Implemented Interfaces:

public class XhrPollingTransport
extends io.netty.channel.ChannelHandlerAdapter

XMLHttpRequest (XHR) Polling is a transport where there is no open connection between the client and the server. Instead the client will issue a new request for polling from and sending data to the SockJS service. This handler is responsible for handling Frames and sending the content back to the client. These frames are generated by the SockJS session handling.
