Redirect using htaccess based on referrer

Question

We only want users from a specific website to use our services. Is there a way to redirect all traffic that does not come from a specific referrer, to a website of our choos

Answer 1

Didn't work for me, I've made this small change to redirect traffic from google:

RewriteEngine On
RewriteCond %{HTTP_REFERER} ^(.*)\.google\.(.*) [NC]
RewriteRule ^(.*)$ https://www.my-site.it/$1 [L,R]
