1. You lose a little bit of the
/index.html link benefit, but you combine all of the benefits of links pointing at both
/ into one pot. You also use the "preferred" root URL for the site - the URL ending with a trailing slash.
2. Redirect the
/ too, otherwise you are promoting duplicate content - the same content at two different URLs. That's also why
non-www redirects to
www. That fixes another duplication.
