Welcome to the Q&A Forum

I have searched google for 'how to setup .htaccess file' and it seems that every website has some variation. For example: RewriteCond %{HTTP_HOST} ^yoursite.com RewriteRule ^(.*)$ http://www.yoursite.com/$1 [R=permanent,L] On SEOMOZ someone posted this: RewriteCond %{HTTP_HOST} !^www.yoursite.com [NC] RewriteRule (.*) http://www.yoursite.com/$1 [L,R=301] On yet another website, I found this: RewriteEngine On RewriteCond %{HTTP_HOST} !^your-site.com$ [NC] RewriteRule ^(.*)$ http://your-site.com/$1 [L,R=301] As you can see there are slight differences. Which one do I use? I'm on Apache CentOS and I have HTML5 websites and several Joomla! wesites. Would the HTACCESS File be different for both?
