How do I clear user's cache [desktop]

Hi,

After upgrading my game,do anyone know how to clear user's cache (or stop them cached my game) so they can use newest version of my game?

If not possible, do you know how long does their cache will be expired?

Thanks!

need same stuff

You don't have control over their cache, but you can recommend that players use "Incognito Mode" (Chrome), "Private Browsing Mode" (Safari), "InPrivate Mode" (Microsoft Edge), or similar to prevent caching altogether.

cjbruce: I think it is inconvenient method for users...I wonder if we can use some JScript to force cleaning user's browsers's cache...!
