Got HTTPS?

It happens that there's somebody implementing the ACME protocol in pure ocaml.
It would be fantastic if we manage to integrate it in Canopy.

With this issue, I would like to open a discussion on the topic.
For what I can see, we need to converge on:

• finding a way to serve a file on a custom path. Right now I deal with this part with
  https://github.com/mmaker/ocaml-acme/blob/master/src/acme_client.ml#L38-41
  and expecting a stat server to be running in parallel, serving that directory.
  This is super easy to do with nginx or apache, but how about canopy?
• launching a Lwt thread, and scheduling future executions of this same command (to renew the certificate)

should this be canopy-specific? I still don't have a clear picture how to integrate/deploy let's encrypt..

Canopy can just as well serve these files required by the ACME protocol without having a file system, it just might be a bit tedious to implement.

I'm working on this in branch feature/letsencrypt.
There's a bunch of comments marked XXX where help would be very much appreciated

It looks awesome !
I will take a deeper look in the evening, thank you very much for your work, it takes Canopy to the next level. :)
What is the status of your branch ? Can it retrieve certs ?
