CURLOPT_COOKIELIST(3) curl_easy_setopt options CURLOPT_COOKIELIST(3)
CURLOPT_COOKIELIST - add to or manipulate cookies held in memory
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIELIST,
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
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-
RELOAD loads all cookies from the files specified by CURLOPT_COOK-
/* 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 */
