On Twitter the other day, I was lamenting the state of OCSP stapling support on Linux servers, and got asked by several people to write-up what I think the requirements are for OCSP stapling support.

1. Support for keeping a long-lived (disk) cache of OCSP responses.

   This should be fairly simple. Any restarting of the service shouldn't blow away previous responses that were obtained. This doesn't need to be disk, just stable - and disk is an easy stable storage for most server

Apache caches an OCSP response for one hour by default. Unfortunately, once the hour is up, the response is purged from the cache, and Apache doesn't attempt to retrieve a new one until the next TLS handshake takes place. That means that if there's a problem contacting the OCSP responder at that moment, Apache is left without an OCSP response to staple. Furthermore, it caches the non-response for 10 minutes (by default), so for the next 10 minutes, no OCSP response will be stapled to your

When using http.Get(), is it really necessary to read the full response body just to close it later?

[9:10] 
The docs keep saying `Caller should close resp.Body when done reading from it.` and I keep seeing code like this:
```
io.Copy(ioutil.Discard, resp.Body)
resp.Body.Close()
```

config_server "https://etcd.local:2379"

service users {
  endpoint: "/users",
  proxy: "{{services.users.ip}}:{{services.users.port}}"
}


# In this example 'services.users' would be a directory with a json key for every user service container / application. 
# Using this we could template the proxy and any other information in the services block, and it would just work with caddy.

Supervisors

A supervisor's main task, is to start a specified process (in a specified environment), watch it running, and do something when it ends - usually based on the exit code.

Systemd

From my experience, the environment setup can be a complex task (consult some config management for the required ports, actualize the config file from the central config management...), and this is where the most featureful supervisor (systemd, AFAIK) falls short:

• it can setup & manage the listening sockets, and pass it to your app (if it can accept it - not hard, just have to be ready for it),
