htaccess Rewrite Questions

Thank you in advance. Here is my question: I placed the following 2 lines of code in my .htaccess file to redirect non-WWW to WWW: RewriteCond %{http_host} ^example.com [nc] RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
Last year, cPanel was upgraded on my server and it now "adds its own code" to my .htaccess file. Here is what is looks like now: RewriteEngine On RewriteCond %{http_host} ^example.com [nc] RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$ RewriteCond %{REQUEST_URI} !^/\.well-known/acme-challenge/[0-9a-zA-Z_-]+$ RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\$ RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301] RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$ RewriteCond %{REQUEST_URI} !^/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
Question 1.) It looks like cPanel only put rewrite 'Conditions'... where is its rewrite 'Rule' ?? Question 2.) Their code interspersed with my code... wouldn't it be better if I pulled out my code and placed it at the beginning, so the end result looks like this? RewriteEngine On RewriteCond %{http_host} ^example.com [nc] RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301] RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$ RewriteCond %{REQUEST_URI} !^/\.well-known/acme-challenge/[0-9a-zA-Z_-]+$ RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\$ RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$ RewriteCond %{REQUEST_URI} !^/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
Question 3.) If I change around the code, do I have to do this every month when cPanel 'refreshes' and/or adds new code? Question 4.) I'm a 'newbie' when it comes to Rewrites... what your your thoughts regarding my questions -- any further suggestions, or questions I failed to ask? Thank you again!
