... as replacements for deprecated CURLOPT_PROTOCOLS and CURLOPT_REDIR_PROTOCOLS as these new ones do not risk running into the 32 bit limit the old ones are facing. CURLINFO_PROTCOOL is now deprecated. The curl tool is updated to use the new options. Added test 1597 to verify the libcurl protocol parser. Closes #8992

.TH CURLOPT_REDIR_PROTOCOLS_STR 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.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 will allow HTTP, HTTPS, FTP and FTPS on redirects (since
|
|
7.65.2). Older versions of libcurl allowed 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.
|
|
|
|
These are the available protocols:
|
|
|
|
DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS,
|
|
POP3, POP3S, RTMP, RTMPE, RTMPS, RTMPT, RTMPTE, RTMPTS, RTSP, SCP, SFTP, SMB,
|
|
SMBS, SMTP, SMTPS, TELNET, TFTP
|
|
|
|
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

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);

}
