Description

Issue by matheuslima Saturday Oct 08, 2016 at 16:27 GMT Originally opened as https://github.com/akka/akka/issues/21638

Today, the response generated looks like:

    HttpResponse(StatusCodes.ServiceUnavailable, entity = "The server was not able " +
      "to produce a timely response to your request.\r\nPlease try again in a short while!")

I need add some headers to all responses generated from my server, but the directive respondWithHeaders seems not work with timed out responses, due the fact the default response is injected by akka http server.

Contributor guide

Research direction
Investigate the Akka HTTP source code to understand how timeout responses are generated and how to allow customization of headers. Look for the relevant handler in the server implementation, possibly in the 'RequestTimeout' or 'HttpServerBluePrint' classes, and propose a configuration option or directive to set custom headers.
