Caching RPMs with pkg-cacher

Introduction
apt-cacher is an excellent proxy server for caching .deb packages. It integrates into apt so that when a package is requested, apt-cacher checks to see if there is a cached copy. If there is, it sends the cached copy. If there isn’t, it downloads the package from the Internet, caches it, and sends it to the requesting server.
While it seems apt-cacher can cache .rpm files, I found pkg-cacher prior to learning about that. This article therefore explains pkg-cacher. Maybe in the future I will see if I can get apt-cacher working in a CentOS environment with working .rpm caching services.
