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 do not 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 (or maybe you have 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_COOKIEJAR(3)

       RELOAD loads all cookies from the files specified by CURLOPT_COOKIEFILE(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 will not 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 */

Cookie file format

       The cookie file format and general cookie concepts in  curl  are  described  online  here:
       https://curl.se/docs/http-cookies.html
