我有ACCESS数据库运行了沉重的存储过程，并返回结果页面，结果将取决于会话变量会话[isShown]例如显示。

I have a page that access Database running a heavy stored procedure and return a result, the result will be displayed depending on a session variable Session["isShown"] for example.

我想使用Ajax调用另一个页面设置：

 xmlhttp.open("POST", "frmCancelWfSearch.aspx", true);
 xmlhttp.send();

如何运行frmCancelWfSearch.aspx asynchrounously来设置会话[isShown]假？

how to run frmCancelWfSearch.aspx asynchrounously to set that Session["isShown"] to false?

推荐答案

实现你的服务器code在 IHttpAsyncHandler ，并落实 IRequiresSessionState 所以你必须访问会话。

Implement your server code in an IHttpAsyncHandler and also implement IRequiresSessionState so you have access to the session.
