Hi @transformsen, do you have the links to the specification/implementation that you mentioned?
Sorry if it's a stupid question, but does "non subresource request" here refer to requests from the origin? I can only find references about "subresource" in the context of "Subresource Integrity".
Thanks for your reply.. Example of non subresource request is from submit. Form submit to new jsp Or servlet page Or any new webpage.
Form non subresource specification recommend to provide replacesClientid. Doc - https://developer.mozilla.org/en-US/docs/Web/API/FetchEvent/replacesClientId Spec - https://w3c.github.io/ServiceWorker/#fetch-event-replacesClientId
But no browser have implemented it. ReplacesClientid would really help for our requirements.
I did not find information in the spec that it can be null. I'm not sure if clientId
can even be the empty string. The IDL in the spec says:
interface FetchEvent : ExtendableEvent {
constructor(DOMString type, FetchEventInit eventInitDict);
[SameObject] readonly attribute Request request;
readonly attribute Promise<any> preloadResponse;
readonly attribute DOMString clientId;
readonly attribute DOMString resultingClientId;
readonly attribute DOMString replacesClientId;
readonly attribute Promise<undefined> handled;
undefined respondWith(Promise<Response> r);
};
And here are the relevant steps in initializing the event:
- Initialize e’s clientId attribute to client’s id.
- If request is a non-subresource request and request’s destination is not "report", initialize e’s resultingClientId attribute to reservedClient’s id, and to the empty string otherwise.
- If request is a navigation request, initialize e’s replacesClientId attribute to request’s replaces client id, and to the empty string otherwise.
