I am looking for the full syntax to use in the .htaccess file for a specific site on my IIS server, running Isapi Rewrite and using per-site htaccess files (or I can add rules to global httpd.config )

The goal: redirect a series of old html pages to a specific per-page counterpart in the new cf site, under a new domain.

Example
==========
User requests: http://www.oldsite-here.com/oldpage-here.html
We direct them to: http://www.newsite-here.com/newpage-here.cfm

As an added twist the initial request might be made with or without the 'www' in front.

What should the full content of my .htaccess file be, for the rule above?
If I can see a working full example for the single rule, I can easily duplicate for the other pages.
