CURLOPT_USERAGENT - set HTTP user-agent header
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_USERAGENT, char *ua);
Pass a pointer to a zero terminated string as parameter. It will be
used to set the User-Agent: header in the HTTP request sent to the
remote server. This can be used to fool servers or scripts. You can
also set any custom header with CURLOPT_HTTPHEADER(3).
The application does not have to keep the string around after setting
NULL, no User-Agent: header is used by default.
CURL *curl = curl_easy_init();
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
curl_easy_setopt(curl, CURLOPT_USERAGENT, "Dark Secret Ninja/1.0");
As long as HTTP is supported
