.TH CURLOPT_COOKIEFILE 3 "17 Jun 2014" libcurl libcurl
|
|
.SH NAME
|
|
CURLOPT_COOKIEFILE \- file name to read cookies from
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIEFILE, char *filename);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a pointer to a null-terminated string as parameter. It should point to
|
|
the file name of your file holding cookie data to read. The cookie data can be
|
|
in either the old Netscape / Mozilla cookie data format or just regular HTTP
|
|
headers (Set-Cookie style) dumped to a file.
|
|
|
|
It also enables the cookie engine, making libcurl parse and send cookies on
|
|
subsequent requests with this handle.
|
|
|
|
By passing the empty string ("") to this option, you enable the cookie engine
|
|
without reading any initial cookies. If you tell libcurl the file name is "-"
|
|
(just a single minus sign), libcurl instead reads from stdin.
|
|
|
|
This option only \fBreads\fP cookies. To make libcurl write cookies to file,
|
|
see \fICURLOPT_COOKIEJAR(3)\fP.
|
|
|
|
If you read cookies from a plain HTTP headers file and it does not specify a
|
|
domain in the Set-Cookie line, then the cookie is not sent since the cookie
|
|
domain cannot match the target URL's. To address this, set a domain in
|
|
Set-Cookie line (doing that includes subdomains) or preferably: use the
|
|
Netscape format.
|
|
|
|
If you use this option multiple times, you add more files to read cookies
|
|
from.
|
|
|
|
The application does not have to keep the string around after setting this
|
|
option.
|
|
|
|
Setting this option to NULL (since 7.77.0) explicitly disables the cookie
|
|
engine and clears the list of files to read cookies from.
|
|
.SH SECURITY
|
|
This document previously mentioned how specifying a non-existing file can also
|
|
enable the cookie engine. While true, we strongly advise against using that
|
|
method as it is too hard to be sure that files that stay that way in the long
|
|
run.
