CURLOPT_REFERER(3) curl_easy_setopt options CURLOPT_REFERER(3)NAME
CURLOPT_REFERER - set the HTTP referer header
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_REFERER, char *where);
DESCRIPTION
Pass a pointer to a zero terminated string as parameter. It will be used to set the Referer: 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 this option.

CURLOPT_HEADER(3) curl_easy_setopt options CURLOPT_HEADER(3)NAME
CURLOPT_HEADER - pass headers to the data stream
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HEADER, long onoff);
DESCRIPTION
Pass in onoff set to 1 to tell the library to include the header in the body output for requests with this handle. This option is relevant
for protocols that actually have headers or other meta-data (like HTTP and FTP).
When asking to get the header info passed to the same callback as the body, it is not possible to accurately separate them again without
detailed knowledge about the protocol in use.
It is often better to use CURLOPT_HEADERFUNCTION(3) to get the header data separately.
While named confusingly similar, CURLOPT_HTTPHEADER(3) is used to set custom HTTP headers!
