How do I set a preferred domain url to avoid the search engines  
duplicate content penalty.

When I go to [http://www.domain.com](http://www.domain.com) or [http://domain.com](http://domain.com) they both work  
and subsequent urls from there.

In the search engines that could become a duplicate content penalty.

Now I can alter the .htaccess by adding by

RewriteBase /

RewriteCond %{HTTP\_HOST} !^www.jasperkooij.com [NC]

RewriteRule ^(.\*)$ [http://www.jasperkooij.com/$1](http://www.jasperkooij.com/$1) [L,R=301]

But can that be made as a default?

That is the easiest way to do it. You could also create a VirtualHost  
for that hostname and put this in it:

Redirect Permanent / [http://jasperkooij.com/](http://jasperkooij.com/)
