Features
Timed in
curl localhost:8080/rest/echo
returns HTTP 200 and responds from the responding service with a 1-second delay, which is within the millau.timeout=2 threshold.
Timed out
The overloaded service responds with a 5-second delay, exceeding the millau.timeout=2 threshold.
Retry Period
Once the overloaded service times out, Millau marks it as unavailable for millau.retry=10 seconds and retries the request with the next available service.
