Jon Topper pointed out a code example bug

 request, and you're free to pass any amount of extra headers that you think

 fit. Adding headers are this easy:

    struct curl_slist *headers;

    struct curl_slist *headers=NULL; /* init to NULL is important */

    headers = curl_slist_append(headers, "Hey-server-hey: how are you?");

    headers = curl_slist_append(headers, "X-silly-content: yes");
