Use the 'Clear storage' action of the Local Storage object.
The 'Clear storage' action could help me to clear the local storage, and it works. But it does not clear our website's cookie and caches, is there any way to clear them? Thank you!
The issue is after we upgrade our game by replace the game folder on our server, and we don't want to change the game's URL, player who played older version will continue load the older version from cache. They can not load the new version.
