Directives are passed to Helmet - see [their documentation](https://helmetjs.github.io/docs/csp/) for more information on the format. Some defaults are added to the configured values so that the application doesn't break. To disable this behaviour, set `addDefaults` to `false`. Further, if `usecdn` is on, some CDN locations are allowed too. By default (`auto`), insecure (HTTP) requests are upgraded to HTTPS via CSP if `useSSL` is on. To change this behaviour, set `upgradeInsecureRequests` to either `true` or `false`. |
