Dear Daniel,

Using --libcurl test.c helped out a lot! Thanks!

It showed me that I could use an option I wasn't aware of [1]. In combination
with [2] it got me what I wanted!

I would like to thank you for responding so promptly!

[1] curl_easy_setopt(hnd, CURLOPT_CUSTOMREQUEST, "GET");
[2] curl_easy_setopt(hnd, CURLOPT_NOBODY, 1L);
