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 op-
       tion.

       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.
