Make subdomain alias of primary domain

[gspark]

I'm not sure if this is the correct forum for this, there are so many to choose from :)

I have an issue i'm trying to resolve, i need to make a sub.domain an alias of the primary domain, reason is so i can use one CMS to manage all sub.domain content. My hosting company doesn't appear to have the features I need to do this, is there a way to do it with htaccess?

i don't want to redirect it, i want to alias it so sub.domain.com points to domain.com url should still read sub.domain.com

If you have configured your DNS zone file to define the subdomain, and if you have a unique IP address for your server, then this may work. Otherwise, you'll have to get your host to define the VirtualServer for the subdomain(s) -- or to define a "wildcard" subdomain for you.
