If you want to use host headers in development with self hosted ASP .NET SignalR 2.0, you can add the hostheader to your hosts file, found in C:\Windows\System32\Drivers\etc
Then use the following adjusted client and server from the tutorial at http://www.asp.net/signalr/overview/getting-started/tutorial-signalr-self-host:
Server
namespace SignalRSelfHost { using System; using Microsoft.AspNet.SignalR; using Microsoft.Owin.Hosting; using Owin; class Program { static void Main(string[] args) { // This will *ONLY* bind to localhost, if you want to bind to all addresses // use http://*:8080 to bind to all addresses. // See http://msdn.microsoft.com/en-us/library/system.net.httplistener.aspx // for more information. //string url = "http://localhost:8080"; string url = "http://rlitest.nl"; using (WebApp.Start<Startup>(url)) { Console.WriteLine("Server running on {0}", url); Console.ReadLine(); } } } class Startup { public void Configuration(IAppBuilder app) { var config = new HubConfiguration(); config.EnableJSONP = true; app.MapSignalR(config); } } public class MyHub : Hub { public void Send(string name, string message) { Clients.All.addMessage(name, message); } } }
Client
<!DOCTYPE html> <html> <head> <title>SignalR Simple Chat</title> <style type="text/css"> .container { background-color: #99CCFF; border: thick solid #808080; padding: 20px; margin: 20px; } </style> </head> <body> <div class="container"> <input type="text" id="message" /> <input type="button" id="sendmessage" value="Send" /> <input type="hidden" id="displayname" /> <ul id="discussion"></ul> </div> <!--Script references. --> <!--Reference the jQuery library. --> <script src="Scripts/jquery-1.6.4.min.js"></script> <!--Reference the SignalR library. --> <script src="Scripts/jquery.signalR-2.0.0-rc1.min.js"></script> <!--Reference the autogenerated SignalR hub script. --> <script src="http://rlitest.nl/signalr/hubs"></script> <!--Add script to update the page and send messages.--> <script type="text/javascript"> $(function () { //Set the hubs URL for the connection //$.connection.hub.url = "http://localhost:8080/signalr"; $.connection.hub.url = "http://rlitest.nl/signalr"; // Declare a proxy to reference the hub. var chat = $.connection.myHub; // Create a function that the hub can call to broadcast messages. chat.client.addMessage = function (name, message) { // Html encode display name and message. var encodedName = $('<div />').text(name).html(); var encodedMsg = $('<div />').text(message).html(); // Add the message to the page. $('#discussion').append('<li><strong>' + encodedName + '</strong>: ' + encodedMsg + '</li>'); }; // Get the user name and store it to prepend to messages. $('#displayname').val(prompt('Enter your name:', '')); // Set initial focus to message input box. $('#message').focus(); // Start the connection. $.connection.hub.start({ jsonp: true }).done(function () { $('#sendmessage').click(function () { // Call the Send method on the hub. chat.server.send($('#displayname').val(), $('#message').val()); // Clear text box and reset focus for next comment. $('#message').val('').focus(); }); }); }); </script> </body> </html>
