Hi,
We noticed this strange thing when using CURLOPT_DNS_SHUFFLE_ADDRESSES together with CURLOPT_CONNECT_TO curl fails with "Couldn't resolve host name”. Now, the reason we want to turn on “shuffling” is for the redirects. So we say, connect to this specific IP address, but in case of redirection, when resolving the hostname of the next target, use shuffling. Is it even possible?
Cheers,
VL
