   *
   * Request internal information from the curl session with this function.  The
   * third argument MUST be a pointer to a long, a pointer to a char * or a
   * pointer to a double (as the documentation describes elsewhere).  The data
   * pointed to will be filled in accordingly and can be relied upon only if the
   * function returns CURLE_OK.  This function is intended to get used *AFTER* a
   * performed transfer, all results from this function are undefined until the
   * transfer is completed.

   * Creates a new curl session handle with the same options set for the handle
   * passed in. Duplicating a handle could only be a matter of cloning data and
   * options, internal state info and things like persistent connections cannot
   * be transferred. It is useful in multithreaded applications when you can run
   * curl_easy_duphandle() for each new thread to avoid a series of identical
   * curl_easy_setopt() invokes in every thread.

   * It does keep: live connections, the Session ID cache, the DNS cache and the
