    public class AuthorizationFilter : AuthorizeAttribute, IAuthorizationFilter
        public void OnAuthorization(AuthorizationContext filterContext)
            if (filterContext.ActionDescriptor.IsDefined(typeof(AllowAnonymousAttribute), true)
                || filterContext.ActionDescriptor.ControllerDescriptor.IsDefined(typeof(AllowAnonymousAttribute), true))
                // Don't check for authorization as AllowAnonymous filter is applied to the action or controller

            // Check for authorization
            if (System.Web.HttpContext.Current.Session["Username"] == null)
                filterContext.Result = new HttpUnauthorizedResult();

            bool isLogged = true;
            if (dataItem != null)
                Session["Username"] = dataItem.Username;
                isLogged = true;
                isLogged = false;
