Hello. I have this Global.asax file. It's placed on the root of my webpage. I have a problem with getting  protected void Application_BeginRequest(object sender, EventArgs e) to fire.

Aspx pages placed in the root folder, where the Global.asax file is does fire the Application_BeginRequest, but aspx pages that is in subdirectories does not fire it. Why and how to fire with these?


<%@ Application Language="C#" %>
<%@ Import Namespace="util" %>

<script runat="server">
   
    void Application_Start(object sender, EventArgs e)
    {
        // Code that runs on application startup

    }
   
    void Application_End(object sender, EventArgs e)
    {
        //  Code that runs on application shutdown

    }
       
    void Application_Error(object sender, EventArgs e)
    {
        // Code that runs when an unhandled error occurs

    }

    void Session_Start(object sender, EventArgs e)
    {
    }

    void Session_End(object sender, EventArgs e)
    {
        // Code that runs when a session ends.
        // Note: The Session_End event is raised only when the sessionstate mode
        // is set to InProc in the Web.config file. If session mode is set to StateServer
        // or SQLServer, the event is not raised.

    }

    protected void Application_BeginRequest(object sender, EventArgs e)
    {
        // Code that runs when a new session is started
        if (Application["LastScheduledRun"] == null)
        {
            Application["LastScheduledRun"] = DateTime.Now;
            //Label1.Text = "No send. First time." + Application["LastScheduledRun"];
            Email mail = new Email();
            mail.SendMail();
        }
        else
        {
            //Label1.Text += "Will run at first hit after 00:00 O'clock." + (((TimeSpan)(DateTime.Now - Convert.ToDateTime(Application["LastScheduledRun"]))).Minutes);
        }

        if ((((TimeSpan)(DateTime.Now - Convert.ToDateTime(Application["LastScheduledRun"]))).Minutes) > 0)
        {
            Email mail = new Email();
            mail.SendMail();

            Application.Lock();
            Application["LastScheduledRun"] = DateTime.Now;
            Application.UnLock();
            //Label1.Text = "Mail is sent at:" + Application["LastScheduledRun"];
        }        
    }
</script>

Is this 2.0 with the Web Site model or the Web Application model?

If you are using Server.Transfer to redirect to the page, it doesn't fire, but for Response.Redirect is does.

I thought when all kinds of all aspx pages in the project loaded/requested that Application_BeginRequestwould fire.

Here is a possible explanation:

Using server.Transfer() from Application_BeginRequest harm session
http://weblogs.asp.net/ngur/archive/2004/06/24/164771.aspx

Well I know it little bit twisted but If it happened to one of us, probably it could be happened to others. If for some reason you need to catch request in pipeline before page is called and you choose to use Application BeginRequest event. Using server transfer to transfer request to other page from that event will end up without session object and session cookies. Doing so you bypass regular request pipeline and simply don’t call session module who responsible for sessions handling.

You can overcome this behavior by catching application PreRequestHandlerExecute which occurred before calling handlers such as page or web service. At this pipeline step session has been initializing and you won't get session buggy behavior.

No, I am talking about how you get your pages in sub-folders to show, since they are the startup page.  How are you changing to those pages?  Server.Transfer?  Response.Redirect?
