| .TH CURLOPT_REDIR_PROTOCOLS_STR 3 "19 Jun 2014" libcurl libcurl |
| .SH NAME |
| CURLOPT_REDIR_PROTOCOLS_STR \- protocols allowed to redirect to |
| .SH SYNOPSIS |
| .nf |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_setopt(CURL *handle, CURLOPT_REDIR_PROTOCOLS_STR, |
| char *spec); |
| .fi |
| .SH DESCRIPTION |
| Pass a pointer to a string that holds a comma-separated list of case |
| insensitive protocol names (URL schemes). That list limits what protocols |
| libcurl may use in a transfer that it follows to in a redirect when |
| \fICURLOPT_FOLLOWLOCATION(3)\fP is enabled. This option allows applications to |
| limit specific transfers to only be allowed to use a subset of protocols in |
| redirections. |
| |
| Protocols denied by \fICURLOPT_PROTOCOLS_STR(3)\fP are not overridden by this |
| option. |
| |
| By default libcurl allows HTTP, HTTPS, FTP and FTPS on redirects (since |
| 7.65.2). |
| |
| These are the available protocols: |
| |
| DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, |
| MQTT, POP3, POP3S, RTMP, RTMPE, RTMPS, RTMPT, RTMPTE, RTMPTS, RTSP, SCP, SFTP, |
| SMB, SMBS, SMTP, SMTPS, TELNET, TFTP, WS, WSS |
| |
| You can set "ALL" as a short-cut to enable all protocols. Note that by setting |
| all, you may enable protocols that were not supported the day you write this |
| but are introduced in a future libcurl version. |
| |
| If trying to set a non-existing protocol or if no matching protocol at all is |
| set, it returns error. |
| .SH 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. |
| .SH PROTOCOLS |
| All |
| .SH EXAMPLE |
| .nf |
| 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_STR, "http,https"); |
| |
| /* Perform the request */ |
| curl_easy_perform(curl); |
| } |
| .fi |
| .SH AVAILABILITY |
| Added in 7.85.0. |
| .SH RETURN VALUE |
| Returns CURLE_UNKNOWN_OPTION if the option is not implemented, |
| CURLE_UNSUPPORTED_PROTOCOL if a listed protocol is not supported or disabled, |
| CURLE_BAD_FUNCTION_ARGUMENT if no protocol is listed else CURLE_OK. |
