I find out I can use

struct curl_slist *headerlist = curl_slist_append(headerlist, buf);
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headerlist);

to set http header in my request. But how can I set "Cache-Control"
to "only-if-cached" in my http request header?

Moreover, can you please tell me how can I do just check the http response code?
