CURLOPT_UNRESTRICTED_AUTH(3) libcurl 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 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 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 therefore also makes curl trust the
server and sends possibly sensitive credentials to any host the server
points out. And then maybe again and again as the following hosts can
keep redirecting to new hosts.
DEFAULT
