NAME

6       CURLOPT_COOKIELIST - add to or manipulate cookies held in memory
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIELIST,
12                                 char *cookie);
13

DESCRIPTION

15       Pass a char * to a cookie string.
16
17       Such  a cookie can be either a single line in Netscape / Mozilla format
18       or just regular HTTP-style header (Set-Cookie: ...) format.  This  will
19       also  enable  the  cookie  engine.  This adds that single cookie to the
20       internal cookie store.
21
22       Exercise caution if you are using this option  and  multiple  transfers
23       may occur.  If you use the Set-Cookie format and don't specify a domain
24       then the cookie is sent for any domain (even after redirects  are  fol‐
25       lowed)  and cannot be modified by a server-set cookie. If a server sets
26       a cookie of the same name (or maybe you've imported one) then both will
27       be  sent  on  a  future  transfer  to  that server, likely not what you
28       intended. To address these issues set a  domain  in  Set-Cookie  (doing
29       that  will  include sub-domains) or use the Netscape format as shown in
30       EXAMPLE.
31
32       Additionally, there are commands available that perform actions if  you
33       pass in these exact strings:
34
35       ALL    erases all cookies held in memory
36
37
38       SESS   erases all session cookies held in memory
39
40
41       FLUSH  writes  all known cookies to the file specified by CURLOPT_COOK‐
42              IEJAR(3)
43
44
45       RELOAD loads all cookies from  the  files  specified  by  CURLOPT_COOK‐
46              IEFILE(3)

EXAMPLE

56       /* This example shows an inline import of a cookie in Netscape format.
57       You can set the cookie as HttpOnly to prevent XSS attacks by prepending
58       #HttpOnly_ to the hostname. That may be useful if the cookie will later
59       be imported by a browser.

78       before a transfer is performed. Cookies in the list that have the same
79       hostname, path and name as in my_cookie are skipped. That is because
80       libcurl has already imported my_cookie and it's considered a "live"
81       cookie. A live cookie won't be replaced by one read from a file.

86       may have added, deleted or modified cookies by then. The cookies that
87       were skipped on import are not exported.
