 The `accessControlMaxAge` indicates how long a preflight request can be cached.

-### addVaryHeader

 The `addVaryHeader` is used in conjunction with `accessControlAllowOrigin` to determine whether the vary header should be added or modified to demonstrate that server responses can differ beased on the value of the origin header.

-### allowedHosts 
+### `allowedHosts` 

 The `allowedHosts` option lists fully qualified domain names that are allowed.

-### hostsProxyHeaders 
+### `hostsProxyHeaders` 

 The `hostsProxyHeaders` option is a set of header keys that may hold a proxied hostname value for the request.

-### sslRedirect 
+### `sslRedirect` 

 The `sslRedirect` is set to true, then only allow https requests.

-### sslTemporaryRedirect
+### `sslTemporaryRedirect`
                    
 Set the `sslTemporaryRedirect` to `true` to force an SSL redirection using a 302 (instead of a 301).

-### sslHost 
+### `sslHost` 

 The `SSLHost` option is the host name that is used to redirect http requests to https.

-### sslProxyHeaders 
+### `sslProxyHeaders` 

 The `sslProxyHeaders` option is set of header keys with associated values that would indicate a valid https request. Useful when using other proxies with header like: `"X-Forwarded-Proto": "https"`.

 The `stsIncludeSubdomains` is set to true, the `includeSubdomains` will be appended to the Strict-Transport-Security header.

 Set `STSPreload` to true to have the `preload` flag appended to the Strict-Transport-Security header.

-### forceSTSHeader

 Set `frameDeny` to true to add the `X-Frame-Options` header with the value of `DENY`.
 
-### customFrameOptionsValue 
+### `customFrameOptionsValue` 

 The `customFrameOptionsValue` allows the `X-Frame-Options` header value to be set with a custom value. This overrides the FrameDeny option.

 The `publicKey` implements HPKP to prevent MITM attacks with forged certificates. 

-### referrerPolicy
+### `referrerPolicy`

 The `referrerPolicy` allows sites to control when browsers will pass the Referer header to other sites.

-### isDevelopment
+### `isDevelopment`

 Set `isDevelopment` to true when developing. The AllowedHosts, SSL, and STS options can cause some unwanted effects. Usually testing happens on http, not https, and on localhost, not your production domain.  
 If you would like your development environment to mimic production with complete Host blocking, SSL redirects, and STS headers, leave this as false.
