NAME

       CURLOPT_COOKIEFILE - file name to read cookies from

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIEFILE, char *filename);

DESCRIPTION

       Pass  a  pointer  to a zero 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 reads cookies. To make libcurl write cookies to file, see CURLOPT_COOKIEJAR(3).

       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.

DEFAULT

       NULL

         /* get cookies from an existing file */
         curl_easy_setopt(curl, CURLOPT_COOKIEFILE, "/tmp/cookies.txt");
