It's also not very useful if the site is hosted on a shared platform, (e.g. Github Pages, Cloudflare Pages, Netlify, Wordpress, Blogger, etc). It also isn't very useful if the server is hosted behind a [reverse proxy](https://en.wikipedia.org/wiki/Reverse_proxy), which is very common on the modern Internet.
