Redirecting non-www subfolder domain to www on wordpress multisite

Question

I currently have a multisite built in wordpress. The domain is set up to be:

http://www.domain.com

The microsites are set up and built out as:

http://www.domain.com/location-name 

My issues are with the non-www domains. If you go to

http://domain.com/location-name/ or http://domain.com/location-name/about 

it redirects to http://www.domain.com

I need it to redirect to http://www.domain.com/location-name/ or http://www.domain.com/location-name/about

Answer 1

You can use this to force www using your .htaccess file:

RewriteEngine On

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

Make sure you clear your cache before testing this.
