In our company we have web app (backend spring, frontend angularjs) which displays lot of photos and they are used for some evaluations. Default browser is FF. After some time period (10-20min) the working with app is so slowen down that it is almost unusable. In that case user press Ctrl+F5 and it is OK again. The question: exists any javascript method to clear cache or simulate Ctrl+F5 on background WITHOUT showing the confirmation dialog "This page is asking you to confirm that you want to leave..."? Thanks a lot for help.
Regards
