I want to make all of my parked and addon domains and sub domains canonical for better SEO on Google using the .htaccess file.

I used the following lines but it only works for my parked domains and sub domains but not for my addon domains and sub domains, see below:

Code:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
Results:

Add on domains and sub domains failure:

addondomain.com permanently redirects to www.addondomain.com/addondomain.com/ Failure

admin.addondomain.com permanently redirects to www.admin.addondomain.com/addondomain.com/admin/ Failure

Parked domains and sub domains successful:

parkeddomain.com permanently redirects to www.parkeddomain.com Success

admin.parkeddomain.com permanently redirects to www.admin.parkeddomain.com Success

Objective:

One .htaccess file to control the canonical www in all of my parked and addon domains and sub domains.

But I don’t know the correct lines of code to use in my .htaccess file to make this work?

Please help.

Thank you,
Richard Morris
