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 does not send custom nor
       internally generated Authentication: headers on requests done to other hosts than the  one
       used for the initial URL.

       By  default,  libcurl  only  sends  credentials  and Authentication headers to the initial
       hostname 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 CURLOPT_UNRESTRICTED_AUTH(3) to 1L makes
       curl  trust  the  server  and  sends possibly sensitive credentials to any host the server
       points to, possibly again and again as the following hosts can  keep  redirecting  to  new
       hosts.

DEFAULT

       0

EXAMPLE

       int main(void)
       {
         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);
         }
       }
