Hi:

My project use Jetty as a HTTP server.Last year,a problem occurred.
Jetty response two HTTP head in one request,,
and it happened three times.

The first head is:

HTTP/1.1 200 OK
Content-Length: 0

Now ,I add some code in org.eclipse.jetty.io.nio.ChannelEndPoint.gatheringFlush()
while the data contains "Content-Length: 0" I invoke Thread.dumpstack().
The attachments are the network data capture.
How can i resolve the problem ?
thanks
Jetty version 8.1.9-20130131
JDK version 1.6.0.32
OS version Red Hat Enterprise Linux Server release 5.3
Here is my server code:(I use nio)

 Server server = new Server();
 SelectChannelConnector selectConnector = new SelectChannelConnector();
                    	 selectConnector.setSoLingerTime(0);
                         selectConnector.setReuseAddress(true);
                         selectConnector.setRequestBufferSize(2048);
                         selectConnector.setResponseBufferSize(2048);

                         selectConnector.setLowResourcesConnections(2000);
                         selectConnector.setAcceptQueueSize(2000);
                         selectConnector.setPort(portNumber);
//                         selectConnector.setAcceptors(3);
                         log.debug("defaut add servlet mapping with JettyThreadPool : " +  150);
                         selectConnector.setThreadPool( new JettyThreadPool(150) );
                         server.setConnectors(new Connector[]{selectConnector});
                 ServletContextHandler handler = new ServletContextHandler();
                 //contextHandler.setContextPath(contextPath);
                 handler.setContextPath("/");
                 server.setHandler(handler);
                 SessionHandler sessionHandler = new SessionHandler();
                 ServletHandler servletHandler = new ServletHandler();
                 sessionHandler.setHandler(servletHandler);
                 handler.setServletHandler(servletHandler);
                 server.setStopAtShutdown(true);
                 server.setSendServerVersion(sendServerVersion);
                 server.start();
         ServletHolder holder = new ServletHolder(servlet);

         servletHandler.addServlet(holder);

         ServletMapping mapping = new ServletMapping();
         mapping.setServletName(holder.getName());
         String path = uri.getPath();

         if (!path.startsWith("/")) {
             path = '/' + path;
         }

         if (!path.startsWith(contextPath)) {
             path = contextPath + path;
         }

         mapping.setPathSpec(path);
         servletHandler.addServletMapping(mapping);

It's probably better to ask on the Jetty Users' mailing list as appears in the community section of https://www.eclipse.org/jetty/documentation/current/advanced-contributing.html#community
