Service worker in Safari

Question

I have a major problem with service workers, or what I think is a service worker related problem. The problem I have (only in Safari) both on Mac and iOS is that every second time I visit a route I got a 504 (Gateway Timeout) message in the console and no data is fetched from the server.

Thanks in advance,

Answer 1

Disabling etag from server side fixed my issue.

Answer 2

I was having the same problem, and I was able to fix this by delaying the API call (in a component) to be executed 300 milliseconds after the page reload. So my code looks like the following:

ngOnInit() {
    setTimeout(this._sendRequest.bind(this), 300);
}
