CURLOPT_COOKIELIST(3)      curl_easy_setopt options      CURLOPT_COOKIELIST(3)

NAME
       CURLOPT_COOKIELIST - add to or manipulate cookies held in memory

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIELIST,
                                 char *cookie);

DESCRIPTION
       Pass a char * to a cookie string.

       Such  a cookie can be either a single line in Netscape / Mozilla format
       or just regular HTTP-style header (Set-Cookie: ...) format.  This  will
       also  enable  the  cookie  engine.  This adds that single cookie to the
       internal cookie store.

       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  fol-
       lowed)  and cannot be modified by a server-set cookie. If a server sets
       a cookie of the same name (or maybe you've imported one) 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 as shown in
       EXAMPLE.

       Additionally, there are commands available that perform actions if  you
       pass in these exact strings:

       ALL    erases all cookies held in memory

       SESS   erases all session cookies held in memory

       FLUSH  writes  all known cookies to the file specified by CURLOPT_COOK-
              IEJAR(3)

       RELOAD loads all cookies from  the  files  specified  by  CURLOPT_COOK-
              IEFILE(3)

DEFAULT
       NULL

PROTOCOLS
       HTTP

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

       #define SEP  "\t"  /* Tab separates the fields */

       char *my_cookie =
         "example.com"    /* Hostname */
         SEP "FALSE"      /* Include subdomains */
         SEP "/"          /* Path */
         SEP "FALSE"      /* Secure */
         SEP "0"          /* Expiry in epoch time format. 0 == Session */
         SEP "foo"        /* Name */
         SEP "bar";       /* Value */

       /* my_cookie is imported immediately via CURLOPT_COOKIELIST.
       */
       curl_easy_setopt(curl, CURLOPT_COOKIELIST, my_cookie);

       /* The list of cookies in cookies.txt will not be imported until right
       before a transfer is performed. Cookies in the list that have the same
       hostname, path and name as in my_cookie are skipped. That is because
       libcurl has already imported my_cookie and it's considered a "live"
       cookie. A live cookie won't be replaced by one read from a file.
       */
       curl_easy_setopt(curl, CURLOPT_COOKIEFILE, "cookies.txt");  /* import */

       /* Cookies are exported after curl_easy_cleanup is called. The server
       may have added, deleted or modified cookies by then. The cookies that
       were skipped on import are not exported.
       */
       curl_easy_setopt(curl, CURLOPT_COOKIEJAR, "cookies.txt");  /* export */

       curl_easy_perform(curl);  /* cookies imported from cookies.txt */

       curl_easy_cleanup(curl);  /* cookies exported to cookies.txt */
