301 non-www to www in subdirectory

[bolo]

Hi there,

Can't quite pinpoint what I am doing wrong.

I hav a site with htaccess in root and wordpress hosted in /newsite

the code for the root htaccess file is:


# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /newsite/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /newsite/index.php [L]
</IfModule>

the code for the subdirectory htaccess is

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /newsite/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /newsite/index.php [L]
</IfModule>

# END WordPress


I need to 301 redirect non-www to www

can someone please advise on the code I need to use to do this?

I have searched high and low and tested numerous options and all come back with either an internal server error or still no www.

Thanks in advance...
