CURLOPT_REDIR_PROTOCOLS(3) curl_easy_setopt options CURLOPT_REDIR_PROTOCOLS(3)

NAME
       CURLOPT_REDIR_PROTOCOLS - set protocols allowed to redirect to

SYNOPSIS
       #include <curl/curl.h>

       CURLcode  curl_easy_setopt(CURL  *handle, CURLOPT_REDIR_PROTOCOLS, long
       bitmask);

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  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 will allow 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. CURLPROTO_ALL enables
       all protocols on redirect, including those disabled for security.

       These are the available protocol defines:
       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
       All protocols except for FILE, SCP and since 7.40.0 SMB and SMBS.

PROTOCOLS
       All

EXAMPLE
       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);
       }

AVAILABILITY
       Added in 7.19.4, before then it would follow all protocols.

RETURN VALUE
       Returns CURLE_OK if the option is supported,  and  CURLE_UNKNOWN_OPTION
       if not.
