Recently, we took a look at the Caddy Web server. Today, we’re going to back things up a little bit and look at the A from the classic LAMP stack: the Apache Web server.

Apache has a bad reputation for being old, crusty, and low-performance—but this idea mostly stems from the persistence of ancient guides that still show users how to set it up in extremely antiquated ways.
