NOTE: The default value will be used if a field is omitted. Headers are on the format ["Accept", "*"]; The configuration is passed directly to the webserver.

Example configuration

A very simple https configuration (recommended):

{
  "https": {
    "cert": "/etc/ssl/cert.crt",
    "key": "/etc/ssl/key.pem"
  }
}

A very simple http configuration (default):
