I want blog.example.com and blog.example.com/any_garbage_here
to redirect to www.example.com

I have put the following in my htaccess.
index.html does go to root so that part is fine.
non-www does go to www so that part is also fine.
but blog.example.com does not go to example.com
why is it not working? how do I modify this to get it to work?

RewriteEngine On

RewriteCond %{HTTP_HOST} ^blog\.example\.com$
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]

# Redirect non-www to www:
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

RewriteCond %{THE_REQUEST} ^.*/index\.html
RewriteRule ^(.*)index\.html$ /$1 [R=301,L,NC]

Do you have other subdomains that you need to keep? If not, you can simplify everything at this point by letting all redirects fall under a single domain-name-canonicalization rule. It looks like this:

RewriteCond %{HTTP_HOST} !^(www\.example\.com)?$
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]

Typically this will be your very last redirect, where the second-to-last is the index.html redirect. The rules you've quoted are out of order. If there are no surviving subdomains-- as implied by the quoted rules-- the index.html redirect is also a single line plus condition. (The condition may not even be needed if the [NS] flag works for you. Try it.) This one goes right before the domain-name rule.

Incidentally, forms like
are never necessary. Just leave off the anchor along with the .* part. Personally I wouldn't use an [NC] here. If someone asks for "INDEX.html", let them get the 404 they deserve ;)
