htaccess redirect all URLS with parameters

i want to redirect all URLs of my domain to the index.html with parameters. The creator of the software I'm using says you need to write this in you're Virtual Hosts Config:

RewriteEngine On
RewriteBase /
RewriteRule ^index\.html$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.html[L]

Since I have no access to the Virtual Hosts, I thought you can also implement this in the htaccess file.

Thanks for any answers!
