解决方案

使用setTimeout调用您的服务器.确保将处理程序放置得非常小，以免引起服务器过载.

使用AJAX调用服务器.

要在ASP.NET中实现此功能，您需要有一个每5分钟左右执行一次的计时器控件.在执行时，基于结果，使用Javascript，您需要更新计数器.

使用Xml Http请求非常快，faceboos使用它

解决方案

Use setTimeout to call your server. Make sure you place the handler very small so that it does not overload the server.

Call the server using AJAX.

For this to be implemented in ASP.NET, you need to have a timer control that will be executed every 5 min or so. On execution, based on the result, using Javascript, you need to update the counter.

Use Xml Http Request its very fast and faceboos use it
