* Hosts all the files required to build a package (<code>GENTOO_MIRRORS=mirror.example.com/public/gentoo/distfiles</code>)
** Acts as a caching mirror for already downloaded packages from an official mirror, example caching mirror URL https://mirror.example.com/mirror
** Serves fetch-restricted files (<code>dev-java/oracle-jdk-bin</code> for example), to authorized clients
* Files are served via HTTPS
