libcurl's binary interface
ABI - Application Binary Interface
----------------------------------
==================================
"ABI" describes the low-level interface between an application program and a
library. Calling conventions, function arguments, return values, struct
sizes/defines and more.

Upgrades
--------
In the vast majority of all cases, a typical libcurl upgrade does not break
the ABI at all. Your application can remain using libcurl just as before,
only with less bugs and possibly with added new features. You need to read
the release notes, and if they mention an ABI break/soname bump, you may
have to verify that your application still builds fine and uses libcurl as
it now is defined to work.

Version Numbers
---------------
In libcurl land, you really can't tell by the libcurl version number if that
libcurl is binary compatible or not with another libcurl version.

Soname Bumps
------------
Whenever there are changes done to the library that will cause an ABI
breakage, that may require your application to get attention or possibly be
changed to adhere to new things, we will bump the soname. Then the library
will get a different output name and thus can in fact be installed in
parallel with an older installed lib (on most systems). Thus, old
applications built against the previous ABI version will remain working and
using the older lib, while newer applications build and use the newer one.

never do it again.

Downgrades
----------
Going to an older libcurl version from one you're currently using can be a
tricky thing. Mostly we add features and options to newer libcurls as that
won't break ABI or hamper existing applications. This has the implication
that going backwards may get you in a situation where you pick a libcurl
that doesn't support the options your application needs. Or possibly you
even downgrade so far so you cross an ABI break border and thus a different
soname, and then your application may need to adapt to the modified ABI.

.SH AVAILABLE INFORMATION
The following information can be extracted:
.IP CURLINFO_EFFECTIVE_URL
Pass a pointer to a char pointer to receive the last used effective URL.
Last used URL.
See \fICURLINFO_EFFECTIVE_URL(3)\fP
.IP CURLINFO_RESPONSE_CODE
Pass a pointer to a long to receive the last received HTTP, FTP or SMTP
response code. This option was previously known as CURLINFO_HTTP_CODE in
libcurl 7.10.7 and earlier. The value will be zero if no server response code
has been received. Note that a proxy's CONNECT response should be read with
\fICURLINFO_HTTP_CONNECTCODE\fP and not this.
Last received response code.
See \fICURLINFO_RESPONSE_CODE(3)\fP
Support for SMTP responses added in 7.25.0.
.IP CURLINFO_HTTP_CONNECTCODE
Pass a pointer to a long to receive the last received proxy response code to a
CONNECT request.
Last proxy CONNECT response code.
See \fICURLINFO_HTTP_CONNECTCODE(3)\fP
.IP CURLINFO_FILETIME
Pass a pointer to a long to receive the remote time of the retrieved document
(in number of seconds since 1 jan 1970 in the GMT/UTC time zone). If you get
-1, it can be because of many reasons (unknown, the server hides it or the
server doesn't support the command that tells document time etc) and the time
of the document is unknown. Note that you must tell the server to collect this
information before the transfer is made, by using the
\fICURLOPT_FILETIME(3)\fP option to \fIcurl_easy_setopt(3)\fP or you will
unconditionally get a -1 back. (Added in 7.5)
Remote time of the retrieved document.
See \fICURLINFO_FILETIME(3)\fP
.IP CURLINFO_TOTAL_TIME
Pass a pointer to a double to receive the total time in seconds for the
previous transfer, including name resolving, TCP connect etc.
Total time of previous transfer.
See \fICURLINFO_TOTAL_TIME(3)\fP
.IP CURLINFO_NAMELOOKUP_TIME
Pass a pointer to a double to receive the time, in seconds, it took from the
start until the name resolving was completed.
Time from start until name resolving completed.
See \fICURLINFO_NAMELOOKUP_TIME(3)\fP
.IP CURLINFO_CONNECT_TIME
Pass a pointer to a double to receive the time, in seconds, it took from the
start until the connect to the remote host (or proxy) was completed.
Time from start until remote host or proxy completed.
See \fICURLINFO_CONNECT_TIME(3)\fP
.IP CURLINFO_APPCONNECT_TIME
Pass a pointer to a double to receive the time, in seconds, it took from the
start until the SSL/SSH connect/handshake to the remote host was completed.
This time is most often very near to the PRETRANSFER time, except for cases
such as HTTP pipelining where the pretransfer time can be delayed due to waits
in line for the pipeline and more. (Added in 7.19.0)
Time from start until SSL/SSH handshake completed.
See \fICURLINFO_APPCONNECT_TIME(3)\fP
.IP CURLINFO_PRETRANSFER_TIME
Pass a pointer to a double to receive the time, in seconds, it took from the
start until the file transfer is just about to begin. This includes all
pre-transfer commands and negotiations that are specific to the particular
protocol(s) involved. It does \fInot\fP involve the sending of the protocol-
specific request that triggers a transfer.
Time from start until just before the transfer begins.
See \fICURLINFO_PRETRANSFER_TIME(3)\fP
.IP CURLINFO_STARTTRANSFER_TIME
Pass a pointer to a double to receive the time, in seconds, it took from the
start until the first byte is received by libcurl. This includes
CURLINFO_PRETRANSFER_TIME and also the time the server needs to calculate the
result.
Time from start until just when the first byte is received.
See \fICURLINFO_STARTTRANSFER_TIME(3)\fP
.IP CURLINFO_REDIRECT_TIME
Pass a pointer to a double to receive the total time, in seconds, it took for
all redirection steps include name lookup, connect, pretransfer and transfer
before final transaction was started. CURLINFO_REDIRECT_TIME contains the
complete execution time for multiple redirections. (Added in 7.9.7)
Time taken for all redirect steps before the final transfer.
See \fICURLINFO_REDIRECT_TIME(3)\fP
.IP CURLINFO_REDIRECT_COUNT
Pass a pointer to a long to receive the total number of redirections that were
actually followed. (Added in 7.9.7)
Total number of redirects that were followed.
See \fICURLINFO_REDIRECT_COUNT(3)\fP
.IP CURLINFO_REDIRECT_URL
Pass a pointer to a char pointer to receive the URL a redirect \fIwould\fP
take you to if you would enable \fICURLOPT_FOLLOWLOCATION(3)\fP. This can come
very handy if you think using the built-in libcurl redirect logic isn't good
enough for you but you would still prefer to avoid implementing all the magic
of figuring out the new URL. (Added in 7.18.2)
URL a redirect would take you to, had you enabled redirects.
See \fICURLINFO_REDIRECT_URL(3)\fP
.IP CURLINFO_SIZE_UPLOAD

uploaded.
Number of bytes uploaded.
See \fICURLINFO_SIZE_UPLOAD(3)\fP
.IP CURLINFO_SIZE_DOWNLOAD
Pass a pointer to a double to receive the total amount of bytes that were
downloaded. The amount is only for the latest transfer and will be reset again
for each new transfer. This counts actual payload data, what's also commonly
called body. All meta and header data are excluded and will not be counted in
this number.
Number of bytes downloaded.
See \fICURLINFO_SIZE_DOWNLOAD(3)\fP
.IP CURLINFO_SPEED_DOWNLOAD
Pass a pointer to a double to receive the average download speed that curl
measured for the complete download. Measured in bytes/second.

requests. This is so far only for HTTP requests. Note that this may be more
than one request if FOLLOWLOCATION is true.
Number of bytes sent in the issued HTTP requests.
See \fICURLINFO_REQUEST_SIZE(3)\fP
.IP CURLINFO_SSL_VERIFYRESULT
Pass a pointer to a long to receive the result of the certification
verification that was requested (using the \fICURLOPT_SSL_VERIFYPEER(3)\fP
option to \fIcurl_easy_setopt(3)\fP).
Certificate verification result.
See \fICURLINFO_SSL_VERIFYRESULT(3)\fP
.IP CURLINFO_SSL_ENGINES
Pass the address of a 'struct curl_slist *' to receive a linked-list of
OpenSSL crypto-engines supported. Note that engines are normally implemented
in separate dynamic libraries. Hence not all the returned engines may be
available at run-time. \fBNOTE:\fP you must call \fIcurl_slist_free_all(3)\fP
on the list pointer once you're done with it, as libcurl will not free the
data for you. (Added in 7.12.3)
A list of OpenSSL crypto engines.
See \fICURLINFO_SSL_ENGINES(3)\fP
.IP CURLINFO_CONTENT_LENGTH_DOWNLOAD
Pass a pointer to a double to receive the content-length of the download. This
is the value read from the Content-Length: field. Since 7.19.4, this returns -1
if the size isn't known.
Content length from the Content-Length header.
See \fICURLINFO_CONTENT_LENGTH_DOWNLOAD(3)\fP
.IP CURLINFO_CONTENT_LENGTH_UPLOAD
Pass a pointer to a double to receive the specified size of the upload. Since
7.19.4, this returns -1 if the size isn't known.
Upload size.
See \fICURLINFO_CONTENT_LENGTH_UPLOAD(3)\fP
.IP CURLINFO_CONTENT_TYPE
Pass a pointer to a char pointer to receive the content-type of the downloaded
object. This is the value read from the Content-Type: field. If you get NULL,
it means that the server didn't send a valid Content-Type header or that the
protocol used doesn't support this.
Content type from the Content-Type header.
See \fICURLINFO_CONTENT_TYPE(3)\fP
.IP CURLINFO_PRIVATE
Pass a pointer to a char pointer to receive the pointer to the private data
associated with the curl handle (set with the \fICURLOPT_PRIVATE(3)\fP option
to \fIcurl_easy_setopt(3)\fP). Please note that for internal reasons, the
value is returned as a char pointer, although effectively being a 'void *'.
(Added in 7.10.3)
User's private data pointer.
See \fICURLINFO_PRIVATE(3)\fP
.IP CURLINFO_HTTPAUTH_AVAIL
Pass a pointer to a long to receive a bitmask indicating the authentication
method(s) available. The meaning of the bits is explained in the
\fICURLOPT_HTTPAUTH(3)\fP option for \fIcurl_easy_setopt(3)\fP. (Added in
7.10.8)
Available HTTP authentication methods.
See \fICURLINFO_HTTPAUTH_AVAIL(3)\fP
.IP CURLINFO_PROXYAUTH_AVAIL
Pass a pointer to a long to receive a bitmask indicating the authentication
method(s) available for your proxy authentication. (Added in 7.10.8)
Available HTTP proxy authentication methods.
See \fICURLINFO_PROXYAUTH_AVAIL(3)\fP
.IP CURLINFO_OS_ERRNO
Pass a pointer to a long to receive the errno variable from a connect failure.
Note that the value is only set on failure, it is not reset upon a
successful operation. (Added in 7.12.2)
The errno from the last failure to connect.
See \fICURLINFO_OS_ERRNO(3)\fP
.IP CURLINFO_NUM_CONNECTS
Pass a pointer to a long to receive how many new connections libcurl had to
create to achieve the previous transfer (only the successful connects are
counted). Combined with \fICURLINFO_REDIRECT_COUNT\fP you are able to know
how many times libcurl successfully reused existing connection(s) or not. See
the Connection Options of \fIcurl_easy_setopt(3)\fP to see how libcurl tries
to make persistent connections to save time. (Added in 7.12.3)
Number of new successful connections used for previous transfer.
See \fICURLINFO_NUM_CONNECTS(3)\fP
.IP CURLINFO_PRIMARY_IP
Pass a pointer to a char pointer to receive the pointer to a zero-terminated
string holding the IP address of the most recent connection done with this
\fBcurl\fP handle. This string may be IPv6 if that's enabled. Note that you
get a pointer to a memory area that will be re-used at next request so you
need to copy the string if you want to keep the information. (Added in 7.19.0)
IP address of the last connection.
See \fICURLINFO_PRIMARY_IP(3)\fP
.IP CURLINFO_PRIMARY_PORT
Pass a pointer to a long to receive the destination port of the most recent
connection done with this \fBcurl\fP handle. (Added in 7.21.0)
Port of the last connection.
See \fICURLINFO_PRIMARY_PORT(3)\fP
.IP CURLINFO_LOCAL_IP
Pass a pointer to a char pointer to receive the pointer to a zero-terminated
string holding the local (source) IP address of the most recent connection done
with this \fBcurl\fP handle. This string may be IPv6 if that's enabled. The
same restrictions apply as to \fICURLINFO_PRIMARY_IP\fP. (Added in 7.21.0)
Local-end IP address of last connection.
See \fICURLINFO_LOCAL_IP(3)\fP
.IP CURLINFO_LOCAL_PORT
Pass a pointer to a long to receive the local (source) port of the most recent
connection done with this \fBcurl\fP handle. (Added in 7.21.0)
Local-end port of last connection.
See \fICURLINFO_LOCAL_PORT(3)\fP
.IP CURLINFO_COOKIELIST
Pass a pointer to a 'struct curl_slist *' to receive a linked-list of all
cookies cURL knows (expired ones, too). Don't forget to
\fIcurl_slist_free_all(3)\fP the list after it has been used. If there are no
cookies (cookies for the handle have not been enabled or simply none have been
received) 'struct curl_slist *' will be set to point to NULL. (Added in
7.14.1)
List of all known cookies.
See \fICURLINFO_COOKIELIST(3)\fP
.IP CURLINFO_LASTSOCKET
Pass a pointer to a long to receive the last socket used by this curl
session. If the socket is no longer valid, -1 is returned. When you finish
working with the socket, you must call curl_easy_cleanup() as usual and let
libcurl close the socket and cleanup other resources associated with the
handle. This is typically used in combination with
\fICURLOPT_CONNECT_ONLY(3)\fP. (Added in 7.15.2)
Last socket used.
See \fICURLINFO_LASTSOCKET(3)\fP
.IP CURLINFO_ACTIVESOCKET
The session's active socket.
See \fICURLINFO_ACTIVESOCKET(3)\fP
NOTE: this API is not really working on win64, since the SOCKET type on win64
is 64 bit large while its 'long' is only 32 bits.
.IP CURLINFO_FTP_ENTRY_PATH
Pass a pointer to a char pointer to receive a pointer to a string holding the
path of the entry path. That is the initial path libcurl ended up in when
logging on to the remote FTP server. This stores a NULL as pointer if
something is wrong. (Added in 7.15.4)
The entry path after logging in to an FTP server.
See \fICURLINFO_FTP_ENTRY_PATH(3)\fP
Also works for SFTP since 7.21.4
.IP CURLINFO_CERTINFO
Pass a pointer to a 'struct curl_certinfo *' and you'll get it set to point to
struct that holds a number of linked lists with info about the certificate
chain, assuming you had \fICURLOPT_CERTINFO(3)\fP enabled when the previous
request was done. The struct reports how many certs it found and then you can
extract info for each of those certs by following the linked lists. The info
chain is provided in a series of data in the format "name:content" where the
content is for the specific named data. See also the certinfo.c example. NOTE:
this option is only available in libcurl built with OpenSSL, NSS or GSKit
support. (Added in 7.19.1)
Certificate chain.
See \fICURLINFO_CERTINFO(3)\fP
.IP CURLINFO_TLS_SESSION
Pass a pointer to a 'struct curl_tlssessioninfo *'. The pointer will be
initialized to refer to a 'struct curl_tlssessioninfo *' that will contain an
enum indicating the SSL library used for the handshake and the respective
internal TLS session structure of this underlying SSL library.
This may then be used to extract certificate information in a format
convenient for further processing, such as manual validation. NOTE: this
option may not be available for all SSL backends; unsupported SSL backends
will return 'CURLSSLBACKEND_NONE' to indicate that they are not supported;
this does not mean that no SSL backend was used. (Added in 7.34.0)
.nf
struct curl_tlssessioninfo {
curl_sslbackend backend;
void *internals;
};
.fi
The \fIinternals\fP struct member will point to a TLS library specific pointer
with the following underlying types:
.RS
.IP OpenSSL
SSL_CTX *
.IP GnuTLS
gnutls_session_t
.IP NSS
PRFileDesc *
.IP gskit
gsk_handle
.RE
TLS session info that can be used for further processing.
See \fICURLINFO_TLS_SESSION(3)\fP
.IP CURLINFO_CONDITION_UNMET
Pass a pointer to a long to receive the number 1 if the condition provided in
the previous request didn't match (see \fICURLOPT_TIMECONDITION(3)\fP). Alas,
if this returns a 1 you know that the reason you didn't get data in return is
because it didn't fulfill the condition. The long ths argument points to will
get a zero stored if the condition instead was met. (Added in 7.19.4)
Whether or not a time conditional was met.
See \fICURLINFO_CONDITION_UNMET(3)\fP
.IP CURLINFO_RTSP_SESSION_ID
Pass a pointer to a char pointer to receive a pointer to a string holding the
most recent RTSP Session ID.
RTSP session ID.
See \fICURLINFO_RTSP_SESSION_ID(3)\fP
Applications wishing to resume an RTSP session on another connection should
retrieve this info before closing the active connection.
.IP CURLINFO_RTSP_CLIENT_CSEQ
Pass a pointer to a long to receive the next CSeq that will be used by the
application.
RTSP CSeq that will next be used.
See \fICURLINFO_RTSP_CLIENT_CSEQ(3)\fP
.IP CURLINFO_RTSP_SERVER_CSEQ
Pass a pointer to a long to receive the next server CSeq that will be expected
by the application.
RTSP CSeq that will next be expected.
See \fICURLINFO_RTSP_SERVER_CSEQ(3)\fP
\fI(NOTE: listening for server initiated requests is currently
unimplemented).\fP
Applications wishing to resume an RTSP session on another connection should
retrieve this info before closing the active connection.
.IP CURLINFO_RTSP_CSEQ_RECV
Pass a pointer to a long to receive the most recently received CSeq from the
server. If your application encounters a \fICURLE_RTSP_CSEQ_ERROR\fP then you
may wish to troubleshoot and/or fix the CSeq mismatch by peeking at this value.
RTSP CSeq last received.

.IP Signals
Signals are used for timing out name resolves (during DNS lookup) - when built
without using either the c-ares or threaded resolver backends. When using
multiple threads you should set the \fICURLOPT_NOSIGNAL(3)\fP option to 1L for
all handles. Everything will or might work fine except that timeouts are not
honored during the DNS lookup - which you can work around by building libcurl
with c-ares support. c-ares is a library that provides asynchronous name
resolves. On some platforms, libcurl simply will not function properly
multi-threaded unless this option is set.
.IP "Name resolving"
\fBgethostby* functions and other system calls.\fP These functions, provided
by your operating system, must be thread safe. It is very important that
libcurl can find and use thread safe versions of these and other system calls,
as otherwise it can't function fully thread safe. Some operating systems are
known to have faulty thread implementations. We have previously received
problem reports on *BSD (at least in the past, they may be working fine these
days). Some operating systems that are known to have solid and working thread
support are Linux, Solaris and Windows.
.IP "curl_global_* functions"
These functions are not thread safe. If you are using libcurl with multiple
threads it is especially important that before use you call
\fIcurl_global_init(3)\fP or \fIcurl_global_init_mem(3)\fP to explicitly
initialize the library and its dependents, rather than rely on the "lazy"
fail-safe initialization that takes place the first time
\fIcurl_easy_init(3)\fP is called. For an in-depth explanation refer to
\fIlibcurl(3)\fP section \fBGLOBAL CONSTANTS\fP.
.IP "Memory functions"
These functions, provided either by your operating system or your own
replacements, must be thread safe. You can use \fIcurl_global_init_mem(3)\fP
to set your own replacement memory functions.
.IP Non-safe functions

.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_ACTIVESOCKET,
curl_socket_t *socket);
.SH DESCRIPTION
Pass a pointer to a curl_socket_t to receive the active socket used by this
curl session. If the socket is no longer valid, \fICURL_SOCKET_BAD\fP is
returned. When you finish working with the socket, you must call
\fIcurl_easy_cleanup(3)\fP as usual on the easy handle and let libcurl close
the socket and cleanup other resources associated with the handle. This is
typically used in combination with \fICURLOPT_CONNECT_ONLY(3)\fP.
This option was added as a replacement for \fICURLINFO_LASTSOCKET(3)\fP since
that one isn't working on all platforms.

.TH CURLINFO_FTP_ENTRY_PATH 3 "12 Sep 2015" "libcurl 7.44.0" "curl_easy_getinfo options"
.SH NAME
CURLINFO_FTP_ENTRY_PATH \- get entry path in FTP server
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FTP_ENTRY_PATH, char **path);
.SH DESCRIPTION
Pass a pointer to a char pointer to receive a pointer to a string holding the
path of the entry path. That is the initial path libcurl ended up in when
logging on to the remote FTP server. This stores a NULL as pointer if
something is wrong.
The \fBpath\fP pointer will be NULL or pointing to private memory you MUST NOT
free - it gets freed when you call \fIcurl_easy_cleanup(3)\fP on the
corresponding CURL handle.

.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_LASTSOCKET, long *socket);
.SH DESCRIPTION
Deprecated since 7.45.0. Use \fICURLINFO_ACTIVESOCKET(3)\fP instead.
Pass a pointer to a long to receive the last socket used by this curl
session. If the socket is no longer valid, -1 is returned. When you finish
working with the socket, you must call curl_easy_cleanup() as usual and let
libcurl close the socket and cleanup other resources associated with the
handle. This is typically used in combination with
\fICURLOPT_CONNECT_ONLY(3)\fP.
NOTE: this API is deprecated since it is not working on win64 where the SOCKET
type is 64 bits large while its 'long' is 32 bits. Use the
\fICURLINFO_ACTIVESOCKET(3)\fP instead, if possible.

.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_TLS_SESSION,
struct curl_tlssessioninfo **session);
.SH DESCRIPTION
Pass a pointer to a 'struct curl_tlssessioninfo *'. The pointer will be
initialized to refer to a 'struct curl_tlssessioninfo *' that will contain an
enum indicating the SSL library used for the handshake and the respective
internal TLS session structure of this underlying SSL library.
This may then be used to extract certificate information in a format
convenient for further processing, such as manual validation. NOTE: this
option may not be available for all SSL backends; unsupported SSL backends
will always return NULL in the \fIinternals\fP pointer to indicate that they
are not supported.
.nf
struct curl_tlssessioninfo {
curl_sslbackend backend;
void *internals;
};
.fi
The \fIbackend\fP struct member is one of the defines in the CURLSSLBACKEND_*
series: CURLSSLBACKEND_NONE (when built without TLS support),
CURLSSLBACKEND_OPENSSL, CURLSSLBACKEND_GNUTLS, CURLSSLBACKEND_NSS,
CURLSSLBACKEND_GSKIT, CURLSSLBACKEND_POLARSSL, CURLSSLBACKEND_CYASSL,
CURLSSLBACKEND_SCHANNEL, CURLSSLBACKEND_DARWINSSL or
CURLSSLBACKEND_AXTLS. (Note that the OpenSSL forks are all reported as just
OpenSSL here.)
The \fIinternals\fP struct member will point to a TLS library specific pointer
with the following underlying types:
.RS
.IP OpenSSL
SSL_CTX *
.IP GnuTLS
gnutls_session_t
.IP NSS
PRFileDesc *
.IP gskit

.SH NAME
CURLOPT_DEFAULT_PROTOCOL \- default protocol to use if the URL is missing a
scheme name
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DEFAULT_PROTOCOL, char
*protocol);
.SH DESCRIPTION
This option tells libcurl to use \fIprotocol\fP 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
\fICURLE_UNSUPPORTED_PROTOCOL\fP when libcurl parses a schemeless URL. Parsing
happens when \fIcurl_easy_perform(3)\fP or \fIcurl_multi_perform(3)\fP is
called. The protocols supported by libcurl will vary depending on how it was
built. Use \fIcurl_version_info(3)\fP 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
\fICURLOPT_URL(3)\fP for details.

A parameter set to 1 tells the library to follow any Location: header that the
server sends as part of a HTTP header in a 3xx response.
A long parameter set to 1 tells the library to follow any Location: header
that the server sends as part of a HTTP header in a 3xx response. The
Location: header can specify a relative or an absolute URL to follow.
This means that libcurl will re-send the same request on the new location and
follow new Location: headers all the way until no more such headers are
returned. \fICURLOPT_MAXREDIRS(3)\fP can be used to limit the number of
redirects libcurl will follow.
libcurl will issue another request for the new URL and follow new Location:
headers all the way until no more such headers are returned.
\fICURLOPT_MAXREDIRS(3)\fP can be used to limit the number of redirects
libcurl will follow.
libcurl can limit to what protocols it will automatically follow. The accepted
protocols are set with \fICURLOPT_REDIR_PROTOCOLS(3)\fP and it excludes the
FILE protocol by default.
libcurl limits what protocols it automatically follows to. The accepted
protocols are set with \fICURLOPT_REDIR_PROTOCOLS(3)\fP. By default libcurl
will allow all protocols on redirect except those disabled for security
reasons: Since 7.19.4 FILE and SCP are disabled, and since 7.40.0 SMB and SMBS
are also disabled.
When following a Location:, the 3xx response code that redirected it also
dictates which request method it will use in the subsequent request: For 301,
302 and 303 responses libcurl will switch method to GET unless
\fICURLOPT_POSTREDIR(3)\fP instructs libcurl otherwise. All other 3xx codes
will make libcurl send the same method again.
For users who think the existing location following is too naive, too simple
or just lacks features, it is very easy to instead implement your own redirect
follow logic with the use of \fIcurl_easy_getinfo(3)\fP's
\fICURLINFO_REDIRECT_URL\fP option instead of using
