.htaccess

It took me an embarrassingly long time to figure this one out:

Options +FollowSymlinks
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.(.*) [NC]
RewriteCond %{HTTP_HOST} ^(.*) [NC]
RewriteRule ^(.*)$ http://www.%1/$1 [R=301,NC,L]

I’ve recently joined experts-exchange (note the hyphen) as an expert. Gotta keep my mind sharp…
