1134352 - Test Response.useFinalURL in ServiceWorkers

Status: RESOLVED INVALID

(Core :: DOM: Core & HTML, defect)

Description

[Nikhil Marathe [:nsm] (No longer reading bugmail, please needinfo?)]

Response.finalURL has semantics that can only be tested by a ServiceWorker initiated fetch() for a controllee's fetch().

Specifically, consider page A controlled by worker SW:

A:
fetch('/test').then((r) => console.log(r.url))

SW:
onfetch = (e) => {
  e.respondWith(fetch('/troll').then((r) => {
    r.finalURL = true;
    return r;
  })
}

The output will be '/troll' and not '/test' in A, since setting the finalURL means that response's url is not set to request's url.
