I been reading this article https://www.netlify.com/blog/2017/02/23/better-living-through-caching/ about caché.
I read there the fact that netlify uses etag to tell browsers; “there is no changes, you can load this resource from caché.”
I heavily use XHR in my web design https://fastframework.stringmanolo.ga/dev/#projects if you click any file, it’s loaded using xhr.
Is this right to do? Do i have to set other headers too or this just dosn’t work at all using XHR?
If not, what headers should i change using .toml file?
