Government social benefits to persons, a drag into 2022?

Tracking despite an Ad Blocker: Mixpanel through proxy I debated with myself on whether or not to share this. As a user I don't like tracking and block it when I can. But a new startup needs to understand what their users are doing and big companies surely have workarounds in place already... So here goes.
Nginx behind Cloudfront Self-hosting services on EC2 instances can come with unexpected behavior. If the service is hosted using Nginx, it typically expects a "Host" header. If you have Cloudfront between the EC2 instance and the internet (e.g., for caching, delivery, etc.), Cloudfront won't forward the "
