title: Correct way to precache the root url ("/")
body: <p>I'm a bit confused about the correct way to precache the root url, namely "/".</p>
  
  <p>If I use webpack-plugin-workbox to generate the precacheManifest, it doesn't include an entry for "/". "/index.html" is included of course. Now if the user loads the app, precaching kicks in, and the user tries to load the root url without network connectivity, the site won't load since precaching did nothing for the root url. If the user tries to load "/index.html" everything works nicely. But users don't load that url, they load the root url. So how to cache that?</p>
  
  <p>Should I use the <strong><em>navigateFallback: index.html</em></strong> option which, in my understanding, redirects the user to the provided url in case of connectivity loss and cache miss?</p>
  
  <p>Or should I use <strong><em>templatedUrls: { "/": [ "index.html" ] }</em></strong> option which, in my understanding, generates a hash based on the index.html and then caches "/" based on the changing of that hash value?</p>
  
  <p>Or should I use some completely different strategy?</p>
  
  <p>Thanks a million!</p>
