If I write denverprocessservers.net in the browser address field, I get to http://denverprocessservers.net/, and when writing www.denverprocessservers.net I get to http://www.denverprocessservers.net/
So you should be able to decide which url you want to have, with https and with or without www.
It should be enough to use the local (relative) address for the old URL, but the full URL for the new one. And you need to write a new line starting with 'RewriteRule ^' for the domain and for each page.
