CURLOPT_REFERER(3)                  libcurl                 CURLOPT_REFERER(3)


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


PROTOCOLS

       HTTP


EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         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);
       }


AVAILABILITY

       If built with HTTP support


RETURN VALUE

       Returns CURLE_OK if HTTP support is enabled, CURLE_UNKNOWN_OPTION if
       not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
