So the regular curl tool hangs on this URL too?

AM: No, it doesnt. And I have found out my error in the code. (I should have
paid more attention to the curl_easy_setopt manpages first...sigh).
My intention was to do a zero-data POST, so I did
"curl_easy_setopt(hCurl,CURLOPT_POST);" okay, but forgot to set
CURLOPT_POSTFIELDSIZE to 0. Essentially, this meant (I think) that the CURL
framework expected a user-defined callback function to create the post data,
which never happened. So, it blocked after dispatching the request.
Now, I have:
  curl_easy_setopt(hCurl,CURLOPT_POST);
  curl_easy_setopt(hCurl,CURLOPT_POSTFIELDSIZE, 0);
and the program works well. This was well documented in the man pages.
Thanks for pointing me to the right direction of using the command line
"curl" tool.
