How to do long-polling AJAX requests in ASP.NET MVC?
提问by Andrew Arnott
Does anyone know how to code up long-polling AJAX requests (for server PUSH notifications) in ASP.NET MVC? Whenever I do it, it seems that only the last browser to open up a window gets the notifications. As if IIS/ASP.NET were canceling the last request because it was hung or something.
有谁知道如何在 ASP.NET MVC 中编写长轮询 AJAX 请求（用于服务器推送通知）？每当我这样做时，似乎只有最后一个打开窗口的浏览器才会收到通知。好像 IIS/ASP.NET 正在取消最后一个请求，因为它被挂起或其他原因。

I recently wrote a simple example of a Long Polling Chat Serverusing MVC 3 Async Controllers based on a great article by Clay Lenhart
我最近根据Clay Lenhart 的一篇精彩文章编写了一个使用 MVC 3 异步控制器的长轮询聊天服务器的简单示例
You can use the example on a AppHarbor deploymentI set up based on the source from the BitBucket project.
您可以在我根据 BitBucket 项目的源设置的 AppHarbor 部署中使用该示例。
Also, more information available from my blog post explaining the project.
