Retry

The Retry middleware reissues requests a given number of times to a backend server if that server does not reply.
As soon as the server answers, the middleware stops retrying, regardless of the response status. The retry is done to the TCP level. The Retry middleware has an optional configuration to enable an exponential backoff.

Configuration Example​
