Redirecting www to non-www

[eluser]alexbet[/eluser]
Hey CroNiX,

This works great, except for one small thing. When I type in the domain as www.domain.com and when I am redirected to the non-www domain, the URL in the address bar becomes the following:

http://domain.com/index.php/

Is there any way to take avoid having the "index.php" part in the URL when you are redirected? Here is what I have now in the htaccess file:

Code:

RewriteEngine on
RewriteCond $1 !^(index\.php)
RewriteRule ^(.*)$ /index.php/$1 [L]
RewriteCond %{HTTP_HOST} !^domain.com$
RewriteRule (.*) http://domain.com/$1 [R=301,L]

Thanks SO much!
Alex
