From d95f3dc0b117b0677700dae8dd51145c9b6f2d08 Mon Sep 17 00:00:00 2001 From: Rick Deist Date: Sat, 17 Mar 2018 20:10:04 +0100 Subject: resolve: add CURLOPT_DNS_SHUFFLE_ADDRESSES This patch adds CURLOPT_DNS_SHUFFLE_ADDRESSES to explicitly request shuffling of IP addresses returned for a hostname when there is more than one. This is useful when the application knows that a round robin approach is appropriate and is willing to accept the consequences of potentially discarding some preference order returned by the system's implementation.
