.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
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIEFILE, char *filename);
|
|
.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.
|
|
|
|
Exercise caution if you are using this option and multiple transfers may occur.
|
|
If you use the Set-Cookie format and don't specify a domain then the cookie is
|
|
sent for any domain (even after redirects are followed) and cannot be modified
|
|
by a server-set cookie. If a server sets a cookie of the same name then both
|
|
will be sent on a future transfer to that server, likely not what you intended.
|
|
To address these issues set a domain in Set-Cookie (doing that will include
|
|
sub-domains) or 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.
