Description Janos Wartig 2021-12-07 00:34:01 PST
A fetch request on the page that sets the cache: "no-cache" will result in a network error when it is fetched by a Service Worker.
The error that is thrown looks like this:
TypeError: Request header field Cache-Control is not allowed by Access-Control-Allow-Headers

I implemented a simple test page that reproduces the issue here: https://testjanos.app.baqend.com/
The test page registers a simple Service Worker which listens to fetch requests and tries to fetch them.
It also includes the following script tag:
      let options = { method: "POST", cache: "no-cache", mode: "cors", body: '{"weather":true}' };
	  fetch("https://dcinfos-cache.abtasty.com/v1/geoip", options);

Ways to reproduce:
1. Go to https://testjanos.app.baqend.com/
2. Open Service Workers view (Developer -> Service Workers)
3. Refresh the page
4. Observe that resource https://dcinfos-cache.abtasty.com/v1/geoip could not be fetched due to above error (error prited to the Service Worker console)

Is there any fix for this issue?
