Cache policy

I’m delving into site metrics, and seeing an opportunity for a backend/CDN change. It appears there are no TTLs set for any resources both locally and on the CDN. Is this something that can be fixed to further improve performance?

We can add a TTL, although I guess I’d want to think about what the value should be and if there are any side affects. Web browsers will cache photos even without an explicit TTL, so I don’t think this will have a negative performance impact in most cases. Happy to hear recommendations if folks have them.

I wasn’t aware browsers would cache the images, which the bulk of the results were. However there was also no TTL value on the .woff2 font files, and the CSS. In the case of the latter, I’m assuming that may prove problematic if theme/style changes are made as they won’t reflect right away?
