We have developed an AungularJS browser based app and testing with a Client (a group of people from client side), it is hard to convince them, how to "Empty Cache and Hard Reload" (Press F12, then on top right click on Refresh button and choose -Empty Cache and Hard Reload),
For the time, we are testing only on Chrome browser, is there any way to do that using JS, ask to press "Hard reset button" (like document.location.reload(true);)
