Thanks for your response. The below is what I currently have it. But, when I
use www.sc.com/cs then I was able to access it. However, I would like to
restrict it. So, only www.sc.org can go to cs folder, and www.sc.com can go
to dam folder
NameVirtualHost *:7777
<VirtualHost *:7777>
DocumentRoot "/usr/local/apache/htdocs/cs"
ServerName www.sc.org
</VirtualHost>
<VirtualHost *:7777>
DocumentRoot "/usr/local/apache/htdocs/dam"
ServerName www.sc.com
</VirtualHost>
