// CloseNotify is a middleware that cancels ctx when the underlying
// connection has gone away. It can be used to cancel long operations
// on the server when the client disconnects before the response is ready.
//
// Note: this behaviour is standard in Go 1.8+, so the middleware does nothing
// on 1.8+ and exists just for backwards compatibility.
