Как убрать /index.html с главной страницы?

RewriteEngine On

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.html\ HTTP/
RewriteRule ^index\.html$ http://example.com/ [R=301,L]

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.php\ HTTP/
RewriteRule ^index\.php$ http://example.com/ [R=301,L]

if( $_SERVER['REQUEST_URI'] == "/index.php" ) {
 header( "Location: /", TRUE, 301 );
 exit();
 }
