Using Multiple Configuration Files

Include /etc/httpd/conf/perl.conf Include conf.d/*.conf Include siteconf/

It is sometimes useful to split the server configuration into multiple files. The Include directive allows you to include individual files, all of the files in a particular directory, or files matching a certain pattern, as shown in these examples. If a relative path is specified, then it will be considered relative to the path specified by the ServerRoot directive.

This is usually done by Linux distributions that distribute Apache modules as RPMs. Each one of those packages can place its own configuration file in a specific directory, and Apache will automatically pick it up.
