Force refresh cache app

Anyone have any idea how to I can force the user to reload/refresh the page so they clear their cache for the application? I am making frequent updates to our app and many users are not seeing the current forms and other page stuff because they are seeing the prior update. It's becoming an absolute customer support nightmare having every user seeing a different version of the app because we may update the app a few times per week.

I have the same need. I have seen some websites prompt users to refresh the page to receive new updates.
