How to add Cache headers to Cloudfront?

Question

I'm using cloudfront with no special settings. when I run webpagetest, it gives me an "F" for static content. Is there any way to get cloudfront to put out the correct cache headers?

Here are my results from a page that has cloudfront. I'm not sure this is still live

You need to add these headers (max-age or expires) on your origin. It is the origin that decides how long objects should stay in cache
