Question

I have a Webhandler which generates an image on request in my asp.net Project. But if the user directly access the resource, it won\'t trigger the session start Event in the Gl

Answer 1

You can always make a method of the Session_Start and call it

namespace WebFormsApplication1
{
    public class Global : HttpApplication
    {
        void Session_Start(object sender, EventArgs e) 
        {
            Global.StartSession();
        }
    }

    public static class Global 
    {
        public static void StartSession() {

            Session["Test"] = 1;
        }
    }
}

and in your Handler, simply call Global.StartSession();

The Session_Start event is trigerred whenever some server side handler attempts to either read or write to the session. You might try decorating your handler with the IRequiresSessionState marker interface:

public class MyHandler: IHttpHandler, IRequiresSessionState
{
    ...
}
