Foreign Fetch
This is a proposal for invoking service workers for requests that are same-origin with the service worker fetched from cross-origin clients.
Modifications to Fetch
...
On the face of it, it seems step 3, substep 5, of https://fetch.spec.whatwg.org/#http-fetch, needs modifications to check for a foreign fetch enabled service worker before going to the cache/network.
API
[Constructor (DOMString type, optional ForeignFetchEventInit eventInitDict),
Exposed=ServiceWorker]
interface ForeignFetchEvent : ExtendableEvent {
readonly attribute Request request;
};
dictionary ForeignFetchEventInit : ExtendableEventInit {
required Request request;
};
partial interface ServiceWorkerRegistration {
Promise<void> enableForeignFetch();
Promise<void> disableForeignFetch();
);
Note: We cannot extend FetchEvent because that exposes client and messaging functionality which might lead to security issues since current practice is all same-origin messaging when it comes to service workers.
