Apache configuration files

All Plesk-specific Apache configuration files are included in the Apache
system configuration (/etc/httpd/httpd.conf by default) via file
zz010_psa_httpd.conf using the Include directive. The file
zz010_psa_httpd.conf can be located in /etc/apache2/conf.d/ or
/etc/httpd/conf.d/ depending on the operating system.
The following table represents the hierarchy of Apache configuration
files.
