.TH CURLOPT_COOKIEFILE 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.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.
|
|
|
|
Given an empty or non-existing file or by passing the empty string ("") to
|
|
this option, you can enable the cookie engine without reading any initial
|
|
cookies. If you tell libcurl the file name is "-" (just a single minus sign),
|
|
libcurl will instead read from stdin.
|
|
|
|
This option only \fBreads\fP cookies. To make libcurl write cookies to file,
|
|
see \fICURLOPT_COOKIEJAR(3)\fP.
|
|
|
|
If you use the Set-Cookie file format and do not specify a domain then the
|
|
cookie is not sent since the domain will never match. To address this, set a
|
|
domain in Set-Cookie line (doing that will include sub-domains) or preferably:
|
|
use the Netscape format.
|
|
|
|
If you use this option multiple times, you just add more files to read.
|
|
Subsequent files will add more cookies.
|
|
|
|
The application does not have to keep the string around after setting this
|
|
option.
|
|
|
|
Setting this option to NULL will (since 7.77.0) explicitly disable the cookie
|
|
engine and clear the list of files to read cookies from.

NULL
