I'm wondering it's possible to call (trigger) method on the frontend when admin changes something in backend (admin panel)
Suppose that I have banner which has image with 24h cache-validation time. I want to refresh local storage after admin's save action in the banner section and I know that I don't have possibility to get customer's local storage via PHP. I have been done plugin which executed function afterSave only so far but what's next? do you have any ideas
