I needed to redirect globalwindday.org to www.ewea.org/globalwindday

A normal Apache redirect did not work.

For example:
globalwindday.org/faq would redirect to www.ewea.org/globalwindday/faq
This was a page that did not exist so therefore resulted in a 404 error.

Here are the lines added to vhosts.conf to make it work (stripping sub pages):

<VirtualHost *:80>
        ServerName  globalwindday.org
        ServerAlias www.globalwindday.org
        # Redirect permanent / http://www.ewea.org/globalwindday/   <-- This did not work
        RewriteEngine On
        RewriteCond %{HTTP_HOST} globalwindday.org [NC]
        RewriteRule ^(.*)$  http://www.ewea.org/globalwindday/ [R=301,NC]
</VirtualHost>
