Apache: The Definitive Guide, 3rd Edition

Inclusions into the Config file

You may want to include material from elsewhere into the Config file. You either just paste it in, or you use the Include directive:

Include filename
Server config, virtual host, directory, .htaccess

Because it makes it hard to see what the Config file is actually doing, you probably will not want to use this directive until the file gets really complicated — (see, for instance, Chapter 17, where the Config file also has to control the Tomcat Java module).
