When writing an HTTP server using akka-http’s high-level Route API, is there a way to be notified that the request timeout has expired, or to check whether it is expired, or to check how much time remains? In implementing an expensive route, I would like to stop performing work on a request if the request times out.
Akka-http’s request timeout responds to HTTP requests with status code 503 Service Unavailable: “The server was not able to produce a timely response to your request.
Please try again in a short while!” It is configured using akka.http.server.request-timeout, which is 20 s by default.
