Overview
A server that receives web traffic and forwards it to the right app.
Definition
A server that receives web traffic and forwards it to the right app.
Real-world example
Requests to app.example.com hit Caddy on port 443; Caddy forwards to container port 3000 where Next.js listens, while blog.example.com routes to a different container.
Common mistake
Pointing DNS at the app container port directly (3000) instead of the proxy (80/443), which breaks HTTPS automation.
Better-PaaS in practice
Caddy is the default reverse proxy. When you attach a domain in the dashboard, routing and certificate issuance are configured for that app.
FAQ
Is reverse proxy only relevant to Better-PaaS?
No. reverse proxy appears across Docker, cloud platforms, and self-hosted tooling. Better-PaaS exposes the concept in deploy logs, dashboard fields, or docs when it affects your app.
