You want to post the cookie file?

You don't post cookies. Cookies are passed along in regular HTTP headers.
When you tell curl to store cookies in the cookiejar, you also tell curl that
you want to engage its cookie machine. So, it'll parse incoming cookies and
use the proper ones when you do subsequent requests to sites that have
matching cookies.

You don't POST cookies. And yes, if the site requires cookies your request
should include the cookies.

You must be getting the cookies and passing them back, otherwise it isn't
working or the site is ingoring the absense of the cookies in the second
request.

Setting COOKIEJAR will make curl understand incoming cookies. They will not
be saved to the specified file until you do cleanup().

This commented out HTTPPOST attempt is completely wrong.

If you received cookies in your first request that should be used in this
second one, then curl will fix that for you automaticly.

If you switch on VERBOSE I bet you will see just that.
