facing problem in 301 redirect,

[brainpulse]

HI

i have made .htaccess file to redirect non www to www, But i did not get redirect, is there any thing else
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example\.com
RewriteRule ^(.*)$ http://www.example.com/$1 [R=permanent,L]

or i have to check mod_rewrite enabled on/off, where i can do this...

If that is not working on your current particular web hosting provider you need to contact them and specify all information regarding that.
