-@item --retry-on-http-error=@var{code[,code,...]}
-Consider given HTTP response codes as non-fatal, transient errors.
-Supply a comma-separated list of 3-digit HTTP response codes as
-argument. Useful to work around special circumstances where retries
-are required, but the server responds with an error code normally not
-retried by Wget. Such errors might be 503 (Service Unavailable) and
-429 (Too Many Requests). Retries enabled by this option are performed
-subject to the normal retry timing and retry count limitations of
-Wget.
-
-Using this option is intended to support special use cases only and is
-generally not recommended, as it can force retries even in cases where
-the server is actually trying to decrease its load. Please use it
-wisely and only if you know what you are doing.
