I'm not sure what changed with 2.0, but the scheme that worked in CakePHP 
1.2 to integrate SWFUpload no longer works in 2.0. With the old scheme, you 
pass the session ID to beforeFilter and connect with the existing session 
by setting the ID and starting the session. It's explained here: 
http://xpnce.com/?p=69

For whatever reason, this no longer works. I struggled for a while and 
finally found a solution that works:

public function __construct($request = null, $response = null) {
if(isset($_POST['PHPSESSID'])) {
Configure::write('debug', 0);
session_id($_POST['PHPSESSID']);
}
    parent::__construct($request, $response);
}

It appears that the main issue is that, with CakePHP 2.0, the session is 
started before "beforeFilter" and "startupProcess" methods, and once 
started, assigning an existing ID does not allow you to connect to the 
existing session. By the time those methods are called, a new session has 
already been created, and assigning an existing ID simply replaces the new 
ID with the old. So, I had to override the constructor to get the ID set 
before the session is created.

I wanted to share this info in case someone knows a better way to do this, 
and in case anyone else is struggling with it.

Best,
Dyske
