c# - SignalR always using longpolling -


i using signalr 2.0 beta. chrome, firefox, , ie10 see transport being used longpolling.

http://localhost:8080/signalr/poll?transport=longpolling&connectiontoken=123456

i running hub windows service, , have javascript hub proxies making connections client.

server-side code:

webapp.start<startup>("http://*:8080");  public class startup {     public void configuration(iappbuilder app)     {         var config = new hubconfiguration { enablecrossdomain = true };         app.maphubs(config);     } }

client-side code:

function configuremessaging() {  var connectionmain = $.hubconnection('http://localhost:8080'); connectionmain.statechanged(connectionstatechanged); connectionmain.start({ waitforpageload: false, xdomain: false, jsonp: false });  var vmgrhub = connectionmain.createhubproxy("vmgrhub");  $("#broadcast").click(function () {     vmgrhub.invoke('globalmessage', $("#msg").val()); });  vmgrhub.on('addglobalmessage', function (message) {     $("#message").text(message); }); }

in production, application require cross-domain support, in example provided, windows service , javascript client on localhost.

how can websockets work in browsers support it?

thanks!

also note signalr use websockets, iis 8 or iis 8 express must used, , server must using windows 8, windows server 2012, or later.
