NAME

       CURLOPT_REFERER - 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  null-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.

DEFAULT

       NULL

         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

         /* tell it where we found the link to this place */
         curl_easy_setopt(curl, CURLOPT_REFERER, "https://example.com/aboutme.html");

         curl_easy_perform(curl);
       }
