For a web server has multiple DNS name(DNS round robin),I found c-ares-1.10/libcurl7.39 doesn't cache the server dns in a same session, the round robin still works in the session, look like it always query dns server for the web server fqdn instead of use dns cache. The libcurl7.32/c-ares1.9.1 doesn't has the issue, could you please comment if there are the DNS query related changes around the area between the two c-ares/libcurl version? Thanks!
I can't recall any decision or active change that we've made on purpose to not have the DNS cache used (in either of these projects). Sounds like a potential bug to me.
Can you provide a receipe for how to reproduce against a public URL/name? -- / daniel.haxx.se ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
