traefik error page
An adaptation of the error middleware from traefik that works similar but allows to respond from the service only if the response from the real service has no body.
NOTE: this code contains code from the aformentioned middleware.
Configuration
Works similar as in the middleware, but there are extra configuration and the service works differently.
