This article explains an edge case that occurs with fetch (and potentially other APIs exhibiting the same kind of resource retrieval behavior). This step to help reduce silent cross-site user tracking is part of a larger initiative: the Privacy Sandbox. A different method of service worker registration, outside the normal JavaScript execution context, is required. The lambda function that you pass to the .SetIsOriginAllowed () method returns true if an origin is allowed, so always returning true allows any origin to send requests to the api.

Moreover, we'll need to set credentials to true on the server response in order to set the Access-Control-Allow-Origin header to true, which is necessary for the preflight request from the browser to pass and allow the original request to be made. Requiring an opt-in for CORS responses is one step to limit inadvertent exposure, but as a developer you can explicitly make fetch() requests inside your foreignfetch handler that do not use the implied credentials via: There are some additional considerations that affect how your foreign fetch service worker handles requests made from clients of your service.
