Quick .htaccess edit

I want to redirect all inner url to non-www in following .htaccess

How to do it ?

RewriteEngine On
RewriteRule ^([^/]*)/([^/]*)\/$ /game.php?id=$1&title=$2 [L]
RewriteRule ^([^/]*)\/$ /index.php?page=$1 [L]
RewriteRule ^([^/]*)/([^/]*)/([^/]*)\/$ /category.php?cid=$1&page=$2&title=$3 [L]
RewriteRule ^sitemap.xml$ sitemap.php [L]
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1 [R=301,L]

Code (markup):

 

You want to direct all URLs with www to non-www? I see no https, so maybe something like this will work:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.yoursite\.tld [NC]
RewriteRule ^(.*)$ http://yoursite.tld/$1 [L,R=301]

Code (markup):

Replacing "yoursite" and "tld" with the domain and .com or whatever you are using.

 

Generic rule:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.(.+) [NC]
RewriteRule ^(.*) http://%1/$1 [R=301,NE,L]

Code (ApacheConf):
