 _Default_: `''`
 
+#### navigateFallbackWhitelist [Array⟨RegExp⟩] 
+Works to limit the effect of `navigateFallback`, so that the fallback only
+applies to requests for URLs with paths that match at least one
+[`RegExp`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp).
+
+This option is useful if you want to fallback to the cached App Shell for
+certain specific subsections of your site, but not have that behavior apply
+to all of your site's URLs.
+
+For example, if you would like to have `navigateFallback` only apply to
+navigation requests to URLs whose path begins with `/guide/`
+(e.g. `https://example.com/guide/1234`), the following configuration could be
+used:
+
+```js
+navigateFallback: '/shell',
+navigateFallbackWhitelist: [/^\/guide\//]
+```
+
+If set to `[]` (the default), the whitelist will be effectively bypassed, and
+`navigateFallback` will apply to all navigation requests, regardless of URL.
+
+_Default_: `[]`
+
 #### replacePrefix [String]
 Replaces a specified string at the beginning of path URL's at runtime. Use this
 option when you are serving static files from a different directory at runtime
