Refreshing KeyBehaviorCache after triggering a goal

Question

Certain actions the contact does trigger goals. The triggering of the goals should be visible in the public site via profile completion.

However, we're not seeing the triggered goals in the KeyBehaviorCache. We would have to Abandon the session for it to refresh.

After triggering the goal we call 'FlushContactToXdb2'.

How can we refresh the KeyBehaviorCache without abandoning session?

Answer 1

You can test if a goal has been triggered with this code. It looks in KBC and the current session.

public bool IfGoalAlreadyExists(ID goalId)
{

    // this will get all the goals that have ever happened in the past for a user. Basically all history.   
    var behaviorCache = Tracker.Current.Session.Contact.GetKeyBehaviorCache().Goals.Any(x => x.Id == goalId.ToGuid());

    // this is all the goals that have happened on all the current pages, in the current session. So basically KBC + current pages = every goal that has been fired right now, for this user.
    var goalsTriggered = Tracker.Current.Session.Interaction.Pages.SelectMany(x => x.PageEvents).Where(x => x.IsGoal).ToList();
    var pages = goalsTriggered.Any(x => x.PageEventDefinitionId == goalId.ToGuid());

    return behaviorCache || pages;
}

Key behavior cache (KBC) is read-only and is loaded when a session starts. KBC is updated when session is submitted and is not meant to store live data by design. You could try combining it with current session and check goals in both KBC and Tracker.Current.Session.
