Purge and update html5 application cache through javascript

I arrive to this problem quite a lot of times, where some of the users have a corrupt application cache (HTML 5).

I do update the manifest file every time there is a new release still some times some users get a corrupt application cache.

I such a case I want to fully clear what is there in their application cache and load all the fresh content from the server.

Is there a way to that using Javascript?
