copied!<p>Probably it's an encoding issue. Here's a working C# server I wrote:</p> <pre><code>class Program { static void Main(string[] args) { var listener = new TcpListener(IPAddress.Loopback, 8181); listener.Start(); using (var client = listener.AcceptTcpClient()) using (var stream = client.GetStream()) using (var reader = new StreamReader(stream)) using (var writer = new StreamWriter(stream)) { writer.WriteLine("HTTP/1.1 101 Web Socket Protocol Handshake"); writer.WriteLine("Upgrade: WebSocket"); writer.WriteLine("Connection: Upgrade"); writer.WriteLine("WebSocket-Origin: http://localhost:8080"); writer.WriteLine("WebSocket-Location: ws://localhost:8181/websession"); writer.WriteLine(""); } listener.Stop(); } } </code></pre> <p>And the corresponding client hosted on <code>localhost:8080</code>:</p> <pre class="lang-html prettyprint-override"><code><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript"> var socket = new WebSocket('ws://localhost:8181/websession'); socket.onopen = function() { alert('handshake successfully established. May send data now...'); }; socket.onclose = function() { alert('connection closed'); }; </script> </head> <body> </body> </html> </code></pre> <p>This example only establishes the handshake. You will need to tweak the server in order to continue accepting data once the handshake has been established.</p>
