Hi Jimmy,
If I am understanding your question correctly, a good resource is to call the GoDaddy tech support and they can walk you through the steps. My advice would be to consider these steps:
Assuming you are logged in..
New Redirect
FROM:
Domain: www.domain.com/
Path: /index.html
With or without www.prefix
TO:
Prefix: http
Domain: www.domain.com/
I would confirm this with GoDaddy, so you ensure it doesn't create an infinite loop, but this should allow you to accomplish your goal. They are fairly good at a walkthrough and are available 24/7 at (480) 505-8877
Cheers.
