Hi @trendline,

If user will be stayed as logged in until user's first server side action. We currently don't check if user is logged out or not in the client side.

If you want to keep user logged in even if user does not perform any action for a long time, you can create a client side function which calls an empty serverside method with javascript's setInterval. You can do it in 1 minute period, so user will be logged in in that case.

Thanks.

Is there a way that could do this on server side? Before, I set internal to call server method via JavaScript to get data to client, the user could always stayed as logged in. Now, I upgraded my application use SignalR broadcast data to client, and the current logged in user could get notifications if the broadcasted data with an exception, but after a duration, the user will logout automatically, then the user cannot get notifications any more, and logs also recorded some warning information that current user is not logged in the system. Exception like below:

        /// Initializes a new instance of the &lt;see cref=&quot;EquipmentStateCurrentHub&quot;/&gt; class.
        /// &lt;/summary&gt;
        public EquipmentStateCurrentHub(
            IEquipmentStateCurrentCommunicator equipmentStateCurrentCommunicator,
            ILocalizationManager localizationManager)
        {
            _equipmentStateCurrentCommunicator = equipmentStateCurrentCommunicator;
            _localizationManager = localizationManager;

            Logger = NullLogger.Instance;
            AbpSession = NullAbpSession.Instance;
        }

        public async Task&lt;string&gt; GetEquipmentCurentState(GetEquipmentStateCurrentByProcessStageInput input)
        {
            var user = AbpSession.ToUserIdentifier();

            try
            {
                await _equipmentStateCurrentCommunicator.SendEquipmentCurrentStateToClient(input, user);
                return string.Empty;
            }
            catch (UserFriendlyException ex)
            {
                Logger.Warn("Could not send CG conveyor equipment state to client: " + Context.ConnectionId);
                Logger.Warn(ex.ToString(), ex);
                return ex.Message;
            }
            catch (Exception ex)
            {
                Logger.Warn("Could not send CG conveyor equipment state to user: " + Context.ConnectionId);
                Logger.Warn(ex.ToString(), ex);
                return _localizationManager.GetSource("AbpWeb").GetString("InternalServerError");
            }

I am using NullABPSession.Instance as a property injection to get AbpSession, is this way I can get the current login user?

Is there a way could set a long time expirations for AbpSession?

Hi @trendline,

If you want to extend session timeout, you can do it just like any other ASP.NET application. Have you searched on the web for this ?

Not yet, I have changed the notification publish mode, current I only publish the notification to the subscriber, not to a specified user. Using Abp Notification System.

Not any more AbpSession.ToUserIdentifier() being used, but I still could get the exception "current user not logged on the system" in log.

Any suggestions?
