One thing that still interests me is: is there some default expiration time
for the cache? Because I don't see that issue if I wait for 2 minutes.
CURLOPT_DNS_CACHE_TIMEOUT
Pass a long, this sets the timeout in seconds. Name resolves will be kept in
memory and used for this number of seconds. Set to zero to completely
disable caching, or set to -1 to make the cached entries remain forever. By
default,
libcurl caches this info for 60 seconds.
So yes, after 60 seconds it will do a new DNS resolve unless you change the
timeout.
