curl_easy_reset - reset all options of a libcurl session handle
void curl_easy_reset(CURL *handle);
Re-initializes all options previously set on a specified CURL handle to the
default values. This puts back the handle to the same state as it was in when
it was just created with curl_easy_init(3)
It does not change the following information kept in the handle: live
connections, the Session ID cache, the DNS cache, the cookies and shares.
This function was added in libcurl 7.12.1
