You need to tell curl to record/parse incoming cookies, as it doesn't do that
by default.

CURLOPT_COOKIEFILE enables the cookie parser, it also specifies a file to
read initial cookies from. If the file is non-existing or empty, the parser
is enabled and no cookies will exist from the start.

CURLOPT_COOKIEJAR enables the cookie parser and specifies a file in which all
cookies are written to when the session is over. The output file will be
written using the Netscape/Mozilla cookie file format.

CURLOPT_COOKIE is used to set user-specified cookies, exactly the way you
want the receiver to receive them.

I hope this helps.
