I want to redirect 403 to another domain.
IE: I have a program on another domain that has links to our site. The links are local for example:
about.php is on siteB but is not on siteA. I don't want to put full paths of the links in because when I update my navigation file I copy it from the other site to this one. I would rather htaccess do this:
if about.php does not exist 301 redirect to http://www.siteb.com/about.php
and do on. However, I do not want it to redirect on existing files for example index.php should not redirect.
