So if I'm reading you write the entire htaccess file would essentially look like this (on wordpress). Also does it matter if I include www or not? I do use www as preferred version currently.
Code:
RewriteEngine On
RewriteBase /
RewriteRule ^(.*)$ http://newdomain.com/$1 [R=301,L]
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
AddHandler application/x-httpd-php70 .php .php5 .php4 .php3
