Browser filters and extensions look for known domains like 'google-analytics.com' or 'facebook.net'. By setting up a reverse proxy on your own subdomain (e.g., 'metrics.yourcompany.com'), your tracking requests appear as first-party traffic.

How to Implement

• Set up a Cloudflare Worker or Nginx reverse proxy
• Rewrite the incoming request to point to your tracking provider
• Rename the tracking JS file to something unique and non-obvious
