Redirecting index.html to index.php

I’ve searched for an answer to this, but nothing seems to work. I just installed WordPress into the main directory of a site. I’ve got everything working fine. I’ve even redirected the old RSS feed successfully, but I cannot get mystie.com/index.html to redirect to mysite.com/index.php

Going to mysite.com successfully leads to mysite.com/index.php but mysite.com/index.html gives me the WordPress error page.

I tried a number of mod_rewrite rules in my htaccess file but none seem to work.

I tried this based on a mod_rewrite tutorial:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteRule ^index\.html$ /index.php
RewriteRule cbgfeed.rss$ http://comicbookgalaxy.com/?feed=rss2 [R]
</IfModule>

# END WordPress

The last rewrite in there is working, but the previous to last does not.

Can anyone help? I’d really appreciate it.

Thanks.
Derik.
