No? Usually sites pass a cookie back and a Location: header to the page it
wants you to do to after the login.

Well, unfortunalely, we have different issues to deal with here. libcurl
itself allows pretty flexible ways to solve this, but AFAIK the PHP/CURL
module is not offering access to all those.

If there is a Location returned from the login post, then use FOLLOWLOCATION
and have COOKIEFILE set to a non-existing file (makes it read no cookies by
default but parse returened one). When following the Location, it'll use the
proper cookies in the subsequent request.

You should probably consider using the COOKIEJAR option to have the cookies
stored in a cookie file when the handle is closed, and then set that file
with COOKIEFILE on following requests, which makes them use the proper
cookies automaticly.

CURLOPT_COOKIEJAR saves cookies in a file.
CURLOPT_COOKIEFILE reads cookies from a file
CURLOPT_COOKIE sets a cookie in a request.

Oh sure. Been done a million times.
