.TH CURLOPT_REDIR_PROTOCOLS 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_REDIR_PROTOCOLS \- set protocols allowed to redirect to
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_REDIR_PROTOCOLS, long bitmask);
|
|
.SH DESCRIPTION
|
|
Pass a long that holds a bitmask of CURLPROTO_* defines. If used, this bitmask
|
|
limits what protocols libcurl may use in a transfer that it follows to in a
|
|
redirect when \fICURLOPT_FOLLOWLOCATION(3)\fP is enabled. This allows you to
|
|
limit specific transfers to only be allowed to use a subset of protocols in
|
|
redirections.
|
|
|
|
Protocols denied by \fICURLOPT_PROTOCOLS(3)\fP are not overridden by this
|
|
option.
|
|
|
|
By default libcurl will allow HTTP, HTTPS, FTP and FTPS on redirect (7.65.2).
|
|
Older versions of libcurl allowed all protocols on redirect except several
|
|
disabled for security reasons: Since 7.19.4 FILE and SCP are disabled, and
|
|
since 7.40.0 SMB and SMBS are also disabled. \fICURLPROTO_ALL\fP enables all
|
|
protocols on redirect, including those disabled for security.
|
|
|
|
These are the available protocol defines:
