+# 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 protocol bits. 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:
+~~~c
+CURLPROTO_DICT
+CURLPROTO_FILE
+CURLPROTO_FTP
+CURLPROTO_FTPS
+CURLPROTO_GOPHER
+CURLPROTO_HTTP
+CURLPROTO_HTTPS
+CURLPROTO_IMAP
+CURLPROTO_IMAPS
+CURLPROTO_LDAP
+CURLPROTO_LDAPS
+CURLPROTO_POP3
+CURLPROTO_POP3S
+CURLPROTO_RTMP
+CURLPROTO_RTMPE
+CURLPROTO_RTMPS
+CURLPROTO_RTMPT
+CURLPROTO_RTMPTE
+CURLPROTO_RTMPTS
+CURLPROTO_RTSP
+CURLPROTO_SCP
+CURLPROTO_SFTP
+CURLPROTO_SMB
+CURLPROTO_SMBS
+CURLPROTO_SMTP
+CURLPROTO_SMTPS
+CURLPROTO_TELNET
+CURLPROTO_TFTP
+~~~
+
+# DEFAULT
+
+HTTP, HTTPS, FTP and FTPS (Added in 7.65.2).
+
+Older versions defaulted to all protocols except FILE, SCP and since 7.40.0
+SMB and SMBS.
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(int argc, char **argv)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    /* pass in the URL from an external source */
+    curl_easy_setopt(curl, CURLOPT_URL, argv[1]);
+
+    /* only allow redirects to HTTP and HTTPS URLs */
+    curl_easy_setopt(curl, CURLOPT_REDIR_PROTOCOLS,
+                     CURLPROTO_HTTP | CURLPROTO_HTTPS);
+
+    /* Perform the request */
+    curl_easy_perform(curl);
+  }
+}
+~~~
+
+# HISTORY
+
+**CURLPROTO_*** macros became `long` types in 8.16.0, prior to this version
+a `long` cast was necessary when passed to curl_easy_setopt(3).
+
+# DEPRECATED
+
+Deprecated since 7.85.0.
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
