After seven years of www.medo64.com I decided to follow fashion and drop www. I was pleasantly surprised how easy it was.
Since these pages are WordPress-based, first step was simply changing WordPress and Site address. Since I do want all www.medo64.com requests to be redirected, I decided to adjust .htaccess file. For any request with domain other than current one, it will do simple redirect:
RewriteCond %{HTTP_HOST} !^jmedved\.com$ [NC]
RewriteRule ^(.*)$ http://jmedved.com%{REQUEST_URI} [R=301,L]
And that was it. Frankly, I am still shocked how easy everything went.
[2013-08-18: I went back to www.medo64.com; it just looks better to me.]
