Ideally you should be taking advantage of ASP.NET inbuilt authentication features. In doing so, If you were to configure your web.config as such: configuration > …. … location path ="MySecuredPages"> system.web > authorization > deny users ="?"/> authorization > system.web > location > …. …. configuration > authentication mode ="Forms"> forms name ="MyApplication" path ="/" requireSSL ="false" loginUrl ="LogIn.aspx" protection ="All" timeout ="1440" slidingExpiration ="false"/> authentication > Then upon attempting to request MySecuredPages/Menu.aspx you will automatically be re-directed to Login.aspx. In Login.aspx take advantage of the System.Web.Security objects such as FormsAuthenticationTicket, FormsAuthentication Alternatively, I would recommend you build a custom page that checks for user authentication in the OnInit() event (you must override) and have all your secured pages inherit this page: public class SecuredPage : Page { private bool isAuthorised = false ; public bool IsAuthorised { get { return isAuthorised; } set { isAuthorised = value ; } } #region Web Form Designer generated code override protected void OnInit(EventArgs e) { if (! this .Authorised()) { try { throw new UnauthorizedAccessException(); } catch (UnauthorizedAccessException uae) { Server.Transfer("Login.aspx"); } } / InitializeComponent(); base .OnInit(e); } #endregion private bool Authorised() { // check in session OR HttpContext then FormsAuthenticationTicket for userid } } } public class Menu : SecuredPage { … }
