If you can edit the apache configuration, here is an extra measure to
ensure that your PHP scripts get the right 'answer' for
_SERVER['HOST_NAME']

create a virtual host container for josephcrawford.com, use the
ServerAlias directive to make the server respond to requests directed
to 'www'.  Tell Apache to use it's canonical ServerName when
constructing self-referential URLs.  Note this will not prevent people
from browsing the www site, so you still need the mod rewrite if you
want to catch those urls AND force them to be democratic (No Dub-ya).

ServerName josephcrawford.com
ServerAlias www.josephcrawford.com foo.josephcrawford.com mr.josephcrawford.com
UseCanonical true

See http://httpd.apache.org/docs/2.2/mod/core.html#serveralias

If you want to ignore / drop the www requests all together, then of
course you don't need the server alias.

On the other hand however if you do care about catching www traffic,
but you want to force it over to the dub-ya-less domain, then the
first answer (setting up an A record in DNS) is key to resolving those
requests to your host.  Good DNS providers / Registrars make this
relatively simple to do.  Combine the A record with a single Virtual
host definition plus ServerAlias directives (as many as you want)

Hope that helps
