Hi Justin, Thank you for your answer. The thing is, from my understanding, the request context is done once the HTTP response has been returned so if my goroutines rely on this context, it's cancelled as soon as the response is sent. I would like my goroutines to be cancelled only when a graceful shutdown sign is intercepted by the server.
Or maybe I'm wrong but in this case, I would love to see a working example. Thank you!
