According to SEO POINT How to redirect URL

301 non-www to www

RewriteEngine On
ErrorDocument 401 http://wwww.example.com/
ErrorDocument 404 http://www.example.com/
RewriteRule ^index.htm$ http://www.example.com/ [R=301,L]
RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
