301 Redirect for Hyphenated domains - Help

Hi,

I have a domain seo-experts-india.in which is in wordpress blog. I tried all possible ways to redirect it from non www version to www version by editing .htaccess file . The .htaccess file will look like this :

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

I have added codes like this in .htaccess file

<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{HTTP_HOST} ^seo\-experts\-india\.in [NC]
RewriteRule ^(.*) httpwww[dot]seo-experts-india[dot]in/$1 [R=301,L]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

and
<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{HTTP_HOST} ^seo-experts-india.in [NC]
RewriteRule ^(.*)$ httpwww[dot]seo-experts-india[dot]in/$1 [R=301,L]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
