Cache-Control
header is an awfully potent ingredient in web performance. I mis-read the title at first and was waiting to read about HTML caching. Hugh covers it a bit (like how you’d need to be careful doing so on something like a forum, where the content on pages changes rapidly), but I find it something that’s generally under-talked-about. As in, generally, people just don’t cache HTML at all, because it changes the most and it’s risky being the parent of most other cache. I only do it now because Cloudflare handles it. <web-vitals>

They interrupt one or more of the steps.You should be super aware of anything that is render-blocking and only render-block on purpose (like critical CSS) rather than letting it happen by accident.
