Hopefully, I answered my own question, here
I created an htaccess file with the following in it:
Options +FollowSymLinks
RewriteEngine On
#
# redirect index.htm and index.html to / (do this before non-www to www)
#
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9} /.*index.html? HTTP/
RewriteRule ^(.*)index.html?$ http://www.penny-slot-machines.com/$1 [R=301,L]
and it seems to work
Is that the right way to go about it?
