htaccess redirect to file based on referrer

[NetMillion]

how do I redirect all traffic to a specific file in my html directory based on referrer with .htaccess?

I've tried various lines and I can't get it to work.

it's a fuck ton easier to do that with a php function in your index file

not in my case, I need the htaccess syntax
