1 Long: retry 2 Arg: <num> 3 Added: 7.12.3 4 Help: Retry request if transient problems occur 5 Category: curl 6 --- 7 If a transient error is returned when curl tries to perform a transfer, it 8 will retry this number of times before giving up. Setting the number to 0 9 makes curl do no retries (which is the default). Transient error means either: 10 a timeout, an FTP 4xx response code or an HTTP 408, 429, 500, 502, 503 or 504 11 response code. 12 13 When curl is about to retry a transfer, it will first wait one second and then 14 for all forthcoming retries it will double the waiting time until it reaches 15 10 minutes which then will be the delay between the rest of the retries. By 16 using --retry-delay you disable this exponential backoff algorithm. See also 17 --retry-max-time to limit the total time allowed for retries. 18 19 Since curl 7.66.0, curl will comply with the Retry-After: response header if 20 one was present to know when to issue the next retry. 21 22 If this option is used several times, the last one will be used. 23
