how do I make sure that the cache is not stored ? is there a script I can use?

Hi

so I have added on start of layout the clear localstorage

but when I have the game online and I update to a new version, the users see the old version unless they go to the game again (they have already played it) or click on shift R

I looked in the console and it shows that there is a cache storage folder - how do I clean that so that it will show the latest ver?

thank you
