我为asp.net应用程序创建了一个global.asax文件。我在session_start方法中运行一些代码。该代码未执行。在asp.net 2.0中是否使用某种类型的过程来使用global.asax文件？
我有asax文件本身，也有一个代码隐藏文件。
谢谢!
编辑:
asax文件:
<%@ Application Codebehind="Global.asax.cs" Inherits="GrowUp.Global" %>
文件后面的代码:

public Global()
{
InitializeComponent();
}
protected void Application_Start(Object sender, EventArgs e)
{
Application["HostName"] = System.Configuration.ConfigurationSettings.AppSettings["HostName"];
Application["counter"] = 1;
}
protected void Session_Start(Object sender, EventArgs e)
{
// Get the count from the application variable
int counter = int.Parse(Application["counter"].ToString());
//Check if a cookie exists.
if(HttpContext.Current.Request.Cookies["ligdolVersion"] != null)

//If a cookie exists, we need to redirect the user to the respective site.
if(HttpContext.Current.Request.Cookies["ligdolVersion"].ToString() == "new")

Response.StatusCode = 302;
Response.Status = "Moved temporarily";

return;

}
}
else if (counter == 40)
{
// If a cookie does not already exist,
//we need to check if the user is to be allowed to continue to the old site
//or be redirected to the new site.
//Note in a file that a user was redirected, so we can get an estimate of how many are being redirected.
System.IO.TextWriter tw = new System.IO.StreamWriter(@"redirect.log");
tw.WriteLine("Redirected to new site.");
tw.Close();
// Reset counter.
Application["counter"] = 1;
//write cookie made to expire in 30 days, by then the experiment will be over (we hope!).
HttpCookie cookie = new HttpCookie("ligdolVersion");
DateTime dtNow = DateTime.Now;
TimeSpan tsSpan = new TimeSpan(30, 0, 0, 0, 0);
cookie.Expires = dtNow + tsSpan;

最佳答案
问题是代码隐藏文件。一旦将代码内联到asax文件中，它就起作用了。这可能是旧网站项目的唯一解决方案。
