LibGDX/HTML5/GWT Need to clear the cache of the browser to update

Hello,

I can run an app perfectly on my hoster, but everytime I change something I need to “clear google chrome cache” to run the new version of the app.
I tried to add <metas to .html or change something on nocache.js.

How can I automatically update the app in client-side without need to clear the Google Chrome cache?
