httpd - Apache name-based vhost (ServerAlias)

I'm currently looking at the apache documentation regarding virtual host. It gives an example on this page: http://httpd.apache.org/docs/2.0/vhosts/name-based.html

The example they show is:

ServerName www.domain.tld
ServerAlias domain.tld *.domain.tld
DocumentRoot /www/domain

Wouldn't it work also with this type of config?:

ServerName *.domain.tld
DocumentRoot /www/domain

Or this:

ServerName domain.tld
ServerAlias *.domain.tld

DocumentRoot /www/domain

Answer

You can't use wildcards to specify ServerName as it has to be a FQDN. Your first example with ServerName *.domain.tld will not work as this is not a FQDN. Your second example will work and is quite a common configuration.

One thing to note is that apache processes these directives from top to bottom in the order they are defined and will act upon the first match.
