There is a line in the file /etc/sysconfig/apache2
like this: APACHE_CONF_INCLUDE_FILES=""
which I changed to: APACHE_CONF_INCLUDE_FILES="/etc/apache2/httpd.conf.local"
But I don't know when this file gets included in relation to the httpd.conf file. E.g. Does httpd.conf.local get read before httpd.conf, after httpd.conf or is it slotted somewhere in the middle.
