[cobalt-users] translating subdomain name to username

["Jim Carey" <ozbcoz@xxxxxxxxxxxxxxxx>]

Hi,

I would like to be able to setup a site where I can translate the hostname
to a username and then use that area as my doument root.

ie www.mydomain.com and mydomain.com go to std root
sales.mydomain.com -> /home/sites/www.mydomain.com/users/sales/web
info.mydomain.com -> /home/sites/www.mydomain.com/users/info/web

etc

any ideas - can someone point me somewhere where I can figure this ourt ?
(serveralias,rewrites etc)

cheers

Jim Carey
