Tried a few different approaches; the best
was
http://stackoverflow.com/questions/1100343/apache-redirect-from-non-www-to-www
In an Apache config file, e.g. /etc/httpd/conf.d/default.conf for CentOS
users --
##
## with www
<VirtualHost *:80>
ServerName www.something.com
... lots of other directives
</VirtualHost>
##
## without www -- redirect to www normalize for Google Analytics etc.
## note needs to be AFTER the with-www option so non-matching requests
## like localhost from APIs and command line tools default to that host.
<VirtualHost *:80>
ServerName something.com
Redirect permanent / http://www.something.com/
</VirtualHost>
Main points:
(1) Simpler than the rewrite approach; if you aren't already using
mod_rewrite you can leave it disabled.
(2) If you have valid URLs that start with something other than www.x.com
and x.com (like localhost) you must put the non-www option after the
with-www option. When a server name doesn't match, Apache defaults to the
first server in configuration order that matches the IP address and port.
