positive.code: Health information can be used to check the status of your running application. It is
  often used by monitoring software to alert someone if a production system goes down.
  The default information exposed by the `health` endpoint depends on how it is accessed.
  For an insecure unauthenticated connection a simple '`status`' message is returned, for a
  secure or authenticated connection additional details are also displayed (see
  <<production-ready-health-access-restrictions>> for HTTP details).

  === HTTP health endpoint access restrictions
  The information exposed by the health endpoint varies depending on whether or not it's
  accessed anonymously, and whether or not the enclosing application is secure. 
  By default, when accessed anonymously in a secure application, any details about the
  server's health are hidden and the endpoint will simply indicate whether or not the server
  is up or down. Furthermore, when accessed anonymously, the response is cached for a
  configurable period to prevent the endpoint being used in a denial of service attack.
  The `endpoints.health.time-to-live` property is used to configure the caching period in
  milliseconds. It defaults to 1000, i.e. one second.
  
  The above-described restrictions can be enhanced, thereby allowing only authenticated users full
  access to the health endpoint in a secure application. To do so, set `endpoints.health.sensitive` to `true`.
  Here's a summary of behaviour (with default `sensitive` flag value "false" indicated in bold):
