3 Help: Wait time between retries
6 Make curl sleep this amount of time before each retry when a transfer has
7 failed with a transient error (it changes the default backoff time algorithm
8 between retries). This option is only interesting if --retry is also
9 used. Setting this delay to zero will make curl use the default backoff time.
11 If this option is used several times, the last one will be used.
