The Apache web server has the ability to serve multiple websites from the same IP address, using virtual hosts. Each virtual host can be configured in the main server configuration file, or, thanks to the Include or the IncludeOptional directives, in its own dedicated one. When the number of virtual hosts increases, their management starts to become troublesome. If their configuration is quite similar, we can manage them dynamically, thanks to the mod_vhost_alias module. In this tutorial, we will see how to do it.
