Minimal shortlink service

Using traefik and Caddy

Idea stolen from https://blog.kmonsoor.com/deploying-golink-server-using-Caddy/

Caddyfile

:80 {
    map {path} {redirect-uri} {

        /example    https://www.google.de

        # more
        # ...
    }

    # this below code is required to actually make the above `map` work

    @hasRedir expression `{redirect-uri} != ""`
    redir @hasRedir {redirect-uri}

    # code below is to set the default response if the requested shortlink isn't here
    respond "Thas's an unknown short URL ... :("
}
