Hi Helstedxd
I did a quick google on the problem and it spat this out :-
Code:
RewriteEngine on
RewriteRule index\.html index.php [NC,R]
NC means it is not case sensitive: index=INDEX=InDeX and R is the redirect.
Give it a try and see if it does what you require.

here about a third of the way down the page.
