# `--retry`
|
|
|
|
If a transient error is returned when curl tries to perform a transfer, it
|
|
retries 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 first waits one second and then for
|
|
all forthcoming retries it doubles the waiting time until it reaches 10
|
|
minutes which then remains 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.
|
|
|
|
curl complies with the Retry-After: response header if one was present to know
|
|
when to issue the next retry (added in 7.66.0).
