301 redirect not happening to site

[zuberacorp]

Hello Everyone,

I am trying to redirect my site's non-www page to www page for the sake of SEO.

I have used the below code in my .htaccess file:

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

But, it is redirecting only main page of my site and None of the other pages are being redirected.

Please suggest a way how can I do www-redirect to my whole site.

Thanks
