Windows 8上的IIS 8.0 Express和WebSocket无法正常工作

Question

我尝试使用websockets并将Websocket服务器实现为IHttpHandler。我在Windows8，VisualStudio 2012和IIS 8上工作。每当我尝试使用javascript客户端连接到我的服务器时，我都会获得context.IsWebSocketRequest在ProcessRequest方法中等于false。当我切换到本地IIS服务器时一切正常（context.IsWebSocketRequest为true）。我错过了什么？如何强制IIS Express使用WebSockets？

我的WebSocket服务器实现：

public class WebSocketHandler: IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
       if (context.IsWebSocketRequest)
       {
           context.AcceptWebSocketRequest(ProcessWebSocketRequest,new AspNetWebSocketOptions()
               {
                   RequireSameOrigin = true
               });
       }
    }

    private async Task ProcessWebSocketRequest(AspNetWebSocketContext socketContext)
    {
        var ws = socketContext.WebSocket;
        while (true)
        {
            //Do something...
        }
    }

    public bool IsReusable { get { return false; } }
}

您是否在配置中启用了WebSockets？
