 ## Options
+Setting an option to `false` to cause that rule to be ignored.
 
- - `dnsPrefetchControl` controls browser DNS prefetching
- - `expectCt` for handling Certificate Transparency (Future Feature)
- - `frameguard` to prevent clickjacking
- - `hidePoweredBy` to remove the Server/X-Powered-By header
- - `hsts` for HTTP Strict Transport Security
- - `ieNoOpen` sets X-Download-Options for IE8+
- - `noSniff` to keep clients from sniffing the MIME type
- - `referrerPolicy` to hide the Referer header
- - `xssFilter` adds some small XSS protections
+### All Responses
+- `originAgentCluster`: Default to `{}` to include
+- `referrerPolicy`: Default to `{ policy: 'no-referrer' }`
+- `strictTransportSecurity`: Default to `{ maxAge: 15552000, includeSubDomains: true, preload: true }`
+- X-`dnsPrefetchControl`: Default to `{ allow: false }`
+- X-`downloadOptions`: Default to `{ action: 'noopen' }`

+- `reportTo`: Defaults to `{ maxAge: 31536000, default: '', includeSubdomains: true, csp: '', staple:'', xss: '' }` which won't report by default, needs setting
