CURLOPT_UNRESTRICTED_AUTH(3)

curl_easy_setopt options                          CURLOPT_UNRESTRICTED_AUTH(3)



NAME
       CURLOPT_UNRESTRICTED_AUTH - send credentials to other hosts too

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_UNRESTRICTED_AUTH,
                                 long goahead);

DESCRIPTION
       Set  the  long  gohead parameter to 1L to make libcurl continue to send
       authentication (user+password) credentials  when  following  locations,
       even when hostname changed. This option is meaningful only when setting
       CURLOPT_FOLLOWLOCATION(3).

       Further, when this option is not used or set to 0L,  libcurl  will  not
       send  custom  set  nor  internally generated Authentication: headers on
       requests done to other hosts than the one used for the initial URL.

       By default, libcurl will only send credentials and Authentication head‐
       ers  to  the  initial  host name as given in the original URL, to avoid
       leaking username + password to other sites.

       This option should be used with caution: when curl follows redirects it
       blindly  fetches the next URL as instructed by the server. Setting CUR‐
       LOPT_UNRESTRICTED_AUTH(3) to 1L will therefore also make curl trust the
       server  and  send  possibly  sensitive credentials to a host the server
       points out.

DEFAULT
       0

PROTOCOLS
       HTTP

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
         curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
         curl_easy_setopt(curl, CURLOPT_UNRESTRICTED_AUTH, 1L);
         curl_easy_perform(curl);
       }

AVAILABILITY
       Along with HTTP

RETURN VALUE
       Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
