To redirect ALL files on your domain use this in your .htaccess file if you are on a linux web server:
redirectMatch 301 ^(.*)$ http://www.site.net
redirectMatch permanent ^(.*)$ http://www.site.net
You can also use one of these in your .htaccess file:
redirect 301 /index.php http://www.site.net/index.php
redirect permanent /index.php http://www.site.net/index.php
redirectpermanent /index.php http://www.site.net/index.php
If you need to redirect http://site.net to http://www.site.net and you’ve got mod_rewrite enabled on
your server you can put this in your .htaccess file:
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^site\.net
RewriteRule ^(.*)$ http://www.site.net/$1 [R=permanent,L]
