CURLOPT_REDIR_PROTOCOLS 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
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. By default libcurl will allow all protocols except for FILE and
SCP.
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_SMTP CURLPROTO_SMTPS CURLPROTO_TELNET CURLPROTO_TFTP
DEFAULT
All protocols except for FILE, SCP and SMB.
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.
