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 dis-
       abled, and since 7.40.0 SMB and SMBS are also disabled. CURLPROTO_ALL enables all protocols on redirect, including those disabled for secu-
       rity.

       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.

CURLOPT_DEFAULT_PROTOCOL(3)				     curl_easy_setopt options				       CURLOPT_DEFAULT_PROTOCOL(3)

NAME

       CURLOPT_DEFAULT_PROTOCOL - default protocol to use if the URL is missing a scheme name

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DEFAULT_PROTOCOL, char *protocol);

DESCRIPTION

       This option tells libcurl to use protocol if the URL is missing a scheme name.

       Use one of these protocol (scheme) names:

       dict, file, ftp, ftps, gopher, http, https, imap, imaps, ldap, ldaps, pop3, pop3s, rtsp, scp, sftp, smb, smbs, smtp, smtps, telnet, tftp

       An  unknown  or	unsupported  protocol  causes  error CURLE_UNSUPPORTED_PROTOCOL when libcurl parses a schemeless URL. Parsing happens when
       curl_easy_perform(3) or curl_multi_perform(3) is called. The protocols supported by libcurl will vary depending on how it  was  built.  Use
       curl_version_info(3) if you need a list of protocol names supported by the build of libcurl that you are using.

       This option does not change the default proxy protocol (http).

       Without this option libcurl would make a guess based on the host, see CURLOPT_URL(3) for details.

       The application does not have to keep the string around after setting this option.

DEFAULT

       NULL (make a guess based on the host)

PROTOCOLS

       All

EXAMPLE

       curl = curl_easy_init();
       if(curl) {
	 /* set a URL without a scheme */
	 curl_easy_setopt(curl, CURLOPT_URL, "example.com");

	 /* set the default protocol (scheme) for schemeless URLs */
	 curl_easy_setopt(curl, CURLOPT_DEFAULT_PROTOCOL, "https");

	 /* Perform the request */
	 curl_easy_perform(curl);
       }

AVAILABILITY

       Added in 7.45.0

RETURN VALUE

       CURLE_OK if the option is supported.

       CURLE_OUT_OF_MEMORY if there was insufficient heap space.

       CURLE_UNKNOWN_OPTION if the option is not supported.
