How to allow local scripts to run, with Auth enabled?

I am using SWFUpload and some other scripts that print and download PDF's. The thing is that the machine tries to access a page in order to generate the data for the scripts, but it hits the Authorization requirements. I am using a custom made ip check for this scripts and put them in $this->Auth->allow().

I would like to allow all requests from 127.0.0.1. What is the correct workflow, for custom scripts? Should I allow() all methods and checkIP() or should I make a user for the system and authorize him. I find the last one a little bit to much just for a local connection!

Ok, so I figured out the solution, as it follows:

I wrote an ip check method in core class Security

public static function checkIPBased($userId = false, $ipPool = array()) {
        $permission = FALSE;

        //CHECK BY IP IN IP POOL
        $ipAllowed = array_merge($ipPool, array(
            'localhost',
            '127.0.0.1',
            '::1',
                ));

        foreach ($ipAllowed as $ip):
            if (strpos($_SERVER['REMOTE_ADDR'], $ip) === 0)
                $permission = true;
        endforeach;

        //CHECK IF THE USER IS ACCESING HIS ORDER
        if ($userId && (($userId == AuthComponent::user('id')) || ((int) AuthComponent::user('group_id') === 1)))
            $permission = true;

        return $permission;
    }

After that I wrote in AppController in beforeFilter() the following code:

if (Security::checkIPBased())
            $this->Auth->allow();

This way I am allowing the machine to access all methods while still using Auth Component!
