AWS CDN Expire after caching vs deploy

Question

How do I set an AWS CDN to expire after being cached in the user's browser?

The current method expires after it is deployed...

Expires: new Date(new Date().getTime() + (1000 * 60 * 60 * 24 * 7))

Using Javascript.

I suggest using Cache-Control: max-age=seconds instead of absolute time if I understand your question correctly.
