Hello Team, Our team is handling discourse forums and its experiencing issues of duplicate requests on Chrome and not on Firefox or Safari. I suspect this issue to be related to service workers - workbox. What does the setup look like? We have a domain → https://example.com scripts is hosted at …

Those are not duplicated requests but just a quirk of how Chrome Dev Tools display the service worker proxy. Also you can check the application logs to see that the server don’t get duplicate requests for any routes, like /latest.json. So this is not a bug on Discourse.

Are you sure both requests are hitting the actual network? The second is likely being used to respond to the first.

Yes. In out setup its happening to our analytics code and thus, analytics data is doubled.

Thank-You so much team. Indeed this is a Chrome quirk. Chrome is displaying multiple requests while the data has deduped data.
