[mproxy](https://github.com/kevinmcconnell/mproxy) is a custom minimal proxy designed specifically for Kamal. It has two big advantages over Traefik: 1. Imperative deployments - we tell it to switch from container A to container B, and it waits for container B to start then switches. No need to poll for health checks ourselves or mess around with forcing health checks to fail. 2. Support for multiple apps - as much as possible, configuration is supplied at runtime by the deploy command, allowing us to have multiple apps share an instance of mproxy without conflicting config.
