Website matches all sub-domains?
When this option is enabled, requests for any URL under the domain (like
http://abc.example.com) will return the virtual server's website.
This can be useful if you host an application that can return different
content based on the requested domain name, such as Wordpress MU.
If the virtual server's DNS domain is hosted on this system, Virtualmin
will also add the wildcard * DNS record when Yes is
selected.
