Answer 1

void Application_AuthorizeRequest(object sender, EventArgs e) 
    {
        HttpApplication app = (HttpApplication)sender;
        HttpContext ctx = app.Context;
        //if user authencticated already
        if (ctx.Request.IsAuthenticated == true)
        {
            FormsIdentity id = (FormsIdentity)ctx.User.Identity;
            FormsAuthenticationTicket ticket = id.Ticket;
            string[] roles = ticket.UserData.Split(new char[] { ',' });
            ctx.User = new GenericPrincipal(id, roles);
        }
    }
ticket就是身份验证票，ctx.User 是当前用户
