Simple Apache VirtualHost

VirtualHost
*) http://httpd.apache.org/docs/trunk/vhosts/examples.html

Your server has a single IP address, and multiple aliases (CNAMES) point to this machine in DNS. You want to run a web server for www.example.com and www.example.org on this machine.
Note

Creating virtual host configurations on your Apache server does not magically cause DNS entries to be created for those host names. You must have the names in DNS, resolving to your IP address, or nobody else will be able to see your web site. You can put entries in your hosts file for local testing, but that will work only from the machine with those hosts entries.
