Hi everybody,

I'm trying to figure out the best way to incorporate check for expired license into our Web Application. All our controllers (except for the Login controller) are based on the BaseController class.

Originally we had the following in our BaseController

/// <summary>
        /// Puts the BaseUrl and Culture into the ViewBag for all controllers
        /// </summary>
        /// <param name="filterContext"></param>
        protected override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            base.OnActionExecuting(filterContext);

            ViewBag.OperatorSession = OperatorSession;
            ViewBag.BaseUrl = BaseUrl;
            ViewBag.Culture = System.Threading.Thread.CurrentThread.CurrentUICulture.Name;
            ModalMessageHelper.GetInstance().ResetAcknowledgments();
            //  CheckExpiration(); // no need to do it on every call
            //ViewBag.ModalMessageHelper = null;
            CheckAssignoThresholdViews();
        }

Note the commented call to CheckExpiration. Our License.ActiveLicense.IsValid is a static property which I may check instead. My question is - what is the best method to check for that property - should I use OnAuthorization method instead? Also, I want to re-direct to the ~/DataMaintenance/ImportLicenses page in this case where controller is also based on the BaseController - I am afraid I may go into the infinitive loop?

How should I handle the check for the license correctly to not allow by-passing it?

Thanks a lot in advance.
