htaccess url redirection

[joshis]

Hi,

 

I need some help about .htaccess file.

 

I want to redirect http://www.yourdomain.com to http://yourdomain.com.

 

how to do this?

I have a code, can anyone correct it?

RewriteEngine On 
RewriteCond $1 !^(index\.php|images|css|js|uploads|ckeditor|photos|albums|books|robots\.txt)  
RewriteCond %{HTTP_HOST} ^www\.yourdomain\.com$ [NC]
RewriteRule (.*) http://yourdomain.com/$1 [R=301,L]  

 

I am developing the site using codeigniter

 

Thanks

Arun
