Caddy Middleware Plugin

This is a experimental plugin for Caddy V2 that allow you to proxy HTTP requests to a NATS backed set of backends.

$ cat Caddyfile
{
    order nats last
}

http://:9090 {
        nats /* weather.nats 
}

Now any request to port 9090 will forward to the NATS hosted service cluster.

$ curl http://localhost:9090/city -d '{"city":"london"}' -v
*   Trying ::1...
* TCP_NODELAY set
