Vaddin contents cache control for web browser

I am using vaadin 8.
It looks like vaadin control the response header of “Cache-Control”, I added a “NoCacheFilter” to “/*”,
Everything of my own servlet changed to “no-cache”, but it can’t change anything for vaadin.

some of the “*cache.js” has max-age of 31536000.

Is there any way to change that?

Thank you in advance!

No one can answer my question?

I am really disappointed.
