- Multi: single
- ---
- If a transient error is returned when curl tries to perform a transfer, it
- will retry this number of times before giving up. Setting the number to 0
- makes curl do no retries (which is the default). Transient error means either:
- a timeout, an FTP 4xx response code or an HTTP 408, 429, 500, 502, 503 or 504
- response code.
- When curl is about to retry a transfer, it will first wait one second and then
- for all forthcoming retries it will double the waiting time until it reaches
- 10 minutes which then will be the delay between the rest of the retries. By
- using --retry-delay you disable this exponential backoff algorithm. See also
- --retry-max-time to limit the total time allowed for retries.
- Since curl 7.66.0, curl will comply with the Retry-After: response header if
- one was present to know when to issue the next retry.
