I want to write a short htaccess script that will rewrite the following conditions, but I want it to do so for the whole website, not just the homepage.

EG.

* domain.com redirects to www.domain.org
* www.domain.com redirects to www.domain.org
* domain.org redirects to www.domain.org

Note, it needs to work so all pages of the site are forced to the www.domain.org domain. For example,

domain.org/contact-us/ redirects to www.domain.org/contact-us/

and 

domain.com/about/ redirects to www.domain.org/about/

etc etc

Appreciate your help.

Matt
