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:
|
2021-01-02 18:51:55 +08:00
|
|
|
a timeout, an FTP 4xx response code or an HTTP 408, 429 or 5xx 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.

If this option is used several times, the last one will be used.
