Thanks you, this actually works great! Now I have an other question, are
there any arguments against doing that with ring-jetty? Is there a
possibility that Jetty isolate the requests and those lose context of the
descriptor in-between? Or is it fine as long as it's not run as a servlet?
If so, is this a scenario where using something like
alpeh/http-kit/netty/aloha makes more sense?
