I've got a linux server with 2 devoted Insolvency practitioners which i use to host about 10 different sites with Apache's virtual host abilities. Each site features its own domain title, and that i use NameVirtualHosts to direct demands towards the proper folder according to which domain has been asked for, and something that does not match (like entering among the IP addresses) will get forwarded to a default page using <VirtualHost _default_:*>.

My real question is, since i have have multiple Insolvency practitioners and all sorts of possible demands are handled as virtual hosts, what must i set ServerName to within the httpd.conf file outdoors from the vhosts? Will it even matter?
