   - recommend: set to **false** if your start url always returns same HTML document, then start url will be precached, this will help to speed up first load.
 - dynamicStartUrlRedirect - if your start url redirect to another route such as `/login`, it's recommended to setup this redirected url for the best user experience.

 - fallbacks - config precached routes to fallback when both cache and network not available to serve resources.
