Using Yast to setup virtual servers for apache blew up the
apache config at least for me. OES seems to have many conf file
to implement various tasks for managing the server. In a normal
implementation of Apache on RH you go to the httpd.conf and the
directives. I did this without much luck.

Within the /etc/apache2/httpd.conf at the end of the file is states
create your own conf file and include it in /etc/sysconfig/apache2.

Also there is a /etc/apache2/vhost.d directory with templates.
The apache docs state.....

Main host goes away

If you are adding virtual hosts to an existing web server,
you must also create a <VirtualHost> block for the existing host.

I am trying to find the best way to add virtual servers without
corrupting everything else. Any ideas?
