.TH CURLOPT_UNRESTRICTED_AUTH 3 "17 Jun 2014" libcurl libcurl
|
||
|
|
.SH NAME
|
||
|
|
CURLOPT_UNRESTRICTED_AUTH \- send credentials to other hosts too
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_UNRESTRICTED_AUTH,
|
||
|
|
long goahead);
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Set the long \fIgohead\fP 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
|
||
|
|
\fICURLOPT_FOLLOWLOCATION(3)\fP.
|
||
|
|
|
||
|
|
Further, when this option is not used or set to \fB0L\fP, 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
|
||
|
|
\fICURLOPT_UNRESTRICTED_AUTH(3)\fP 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.
