This is a complicated issue, but I think its best described as:

1) Allow service workers to opt-in to a "concurrent fetch" mode
2) If a navigation will be intercepted by a SW in this mode, then perform a network request while interception occurs.
3) The SW will then have a promise API to get the result of the concurrent network request.
4) The SW will have an API to configure additional headers for the concurrent network request.

For more info see the very long thread here:
Priority: -- → P3
This has been added to the spec as navigation preload.
Summary: Support opt-in parallel network request when navigation will be intercepted by service worker → Implement service worker navigation preload
We need to finish our e10s architectural changes before adding a new feature like this.
