我想打从JavaScript客户端上的周期性后台请求我的Web应用程序（ASP.NET，IIS 7），但我不希望影响到ASP.NET会话超时请求。

I would like to make a periodic background request from JavaScript on the client to my web application (ASP.NET, IIS 7), but I don't want the request to affect the ASP.NET session timeout.

有没有办法做到这一点？

Is there a way to do this?

推荐答案

您必须避免您的要求发送Cookie，因为这是多么会话ID传送。

You have to avoid sending cookies with your request because that's how session ids are transmitted.

如果你有一个xmlHTT prequest对象，你可以通过调用 xmlHTT prequest.setRequestHeader（曲奇，）删除您的cookie头;

If you have an xmlHTTPRequest object, you can remove your cookie header by calling xmlHTTPRequest.setRequestHeader("Cookie", "");
