    Proxy Requests for Local and Remote Service Parity


    High availability apps require that no distinction be made between local and remote services. Attached resources should be accessed by environment variables, and in doing so allow you to swap out one attached resource for another.

    In this lesson we will setup a reverse proxy that directs image path requests and routes them through a defined server URL. By doing so, we decouple server requests for images which allows for easy switching from locally-served image assets to a CDN by simply updating an environment variable.
