Fix new issues found by `proselint`. Also: - silence this technical warning: ``` :0: DeprecationWarning: /home/runner/.proselintrc was found instead of a JSON file. Rename to /home/runner/.proselintrc.json. ``` - fix an input filename. `proselints` fails now if an input file is missing.

# NAME
|
|
|
|
CURLOPT_REDIR_PROTOCOLS - protocols allowed to redirect to
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_REDIR_PROTOCOLS, long bitmask);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
This option is deprecated. We strongly recommend using
|
|
CURLOPT_REDIR_PROTOCOLS_STR(3) instead because this option cannot
|
|
control all available protocols.
|
|
|
|
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 CURLOPT_FOLLOWLOCATION(3) is enabled. This allows you to
|
|
limit specific transfers to only be allowed to use a subset of protocols in
|
|
redirections.
|
|
|
|
Protocols denied by CURLOPT_PROTOCOLS(3) are not overridden by this
|
|
option.
|
|
|
|
By default libcurl allows HTTP, HTTPS, FTP and FTPS on redirect (7.65.2).
|
|
*CURLPROTO_ALL* enables all protocols on redirect, including those
|
|
otherwise disabled for security.
|
|
|
|
These are the available protocol defines:
|
|

CURLPROTO_DICT
|
|
CURLPROTO_FILE
|
|
CURLPROTO_FTP
|
|
CURLPROTO_FTPS
|
