If I have the following Apache configuration and wildcard *. s1.ex.com pointing to the server

<VirtualHost *>
ServerName example.com
DocumentRoot /var/www/example.com
</VirtualHost>

<VirtualHost *>
ServerName example.net
DocumentRoot /home/user2/web/example.net
</VirtualHost>

Is it possible to automatically get the domains example.com.s1.ex.com example.net.s1.ex.com to automatically point to their respective vhost?

Edit: I'm looking for a solution that automatically do the same as if I had added ServerAlias as manually.

You could add a ServerAlias:

<VirtualHost *>
ServerName example.com
ServerAlias example.com.s1.ex.com
DocumentRoot /var/www/example.com
</VirtualHost>

<VirtualHost *>
ServerName example.net
ServerAlias example.net.s1.ex.com
DocumentRoot /home/user2/web/example.net
</VirtualHost>

Also note that wildcard characters (* and ?) are allowed in the argument(s) to ServerAlias, so you could even do "ServerAlias example.com.*" and "ServerAlias example.net.*". – Xhantar Oct 28 '10 at 2:12
I know of ServerAlias. I'm looking for a solution that automatically do the same as if I had added ServerAlias manually. – Christian Oct 28 '10 at 10:03
Got it. If you have a large number of domains and want it to happen automatically, I'm sure that you can do it with mod_rewrite. Unfortunately, I am not a mod_rewrite expert. – Miles Erickson Oct 28 '10 at 14:13

Are you looking for for mass virtual hosting?

Maybe. I'm looking for a solution that will automatically add ServerAlias for all VirtualHost in a specific domain (eg. s1.ex.com) and so the DocumentRoot to be anything for the VirtualHost. In practice, it is a temporary domain name while waiting for DNS. – Christian Oct 28 '10 at 10:09

I think you want mod_vhost_alias.

LoadModule vhost_alias_module /usr/lib/apache2/modules/mod_vhost_alias.so
<VirtualHost *>
  VirtualDocumentRoot /var/www/%-5.0.%-4
</VirtualHost>

example.com.s1.ex.com is now served from /var/www/example.com.
