ummm..... be careful when taking code snippets and standards advice from
a site that doesn't validate and is broken in IE7. Especially when it
promotes a back link campaign IMHO.
However, the code looks correct if that is what you want to do. I would
also make sure that the site is not spiderable via https: so that you
don't get traffic bypassing your rewrite rule (or perhaps a port 443
check to the rewrite rule).

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
Greg I think there's a bit more to it, because most DNS / Hosting setups
place the A record and aliases such that they create distinct copies of
your site (per each alias). Search engines will index www. and non-www
and any additional aliases as different sites, and if there is
duplication will likely drop all but one copy. Due to the way search
engines honor incoming links, you can end up with a site whose existence
in search engines depends on the whim of external factors you can't control.
The rewrite rule above throws a 301 Permanent redirect response code,
which the search engines use to help identify the primary web site that
should be kept in the search index. If you care to maintain a stable
presence in the search engines, you need to be sure you have a single
web site URL.
