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).

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

DEFAULT

PROTOCOLS

  curl_easy_setopt(curl, CURLOPT_UNRESTRICTED_AUTH, 1L);
  curl_easy_perform(curl);
}

RETURN VALUE

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