Planet CakePHP

I am trying to make a simple redirector controller in CakePHP. I'd like the URL to be of the form:

http://example.com/redirector//

For example,

http://example.com/redirector/1/http://www.google.com

The URL that I need to redirect could be more complex, of course, including slashes, parameters and anchors.

I can't seem to be able to figure out how to write the route configuration so that my action would look something like:

class RedirectsController extends AppController {

    function myredirectaction($id, $url) {
        $this->autoRender = false;
        $this->redirect($url);
    }

It seems like whatever I try, the "/"'s in the url-to-redirect-to confuses my route attempt and splits the URL into pieces, and this no longer matches my action definition. What should I do?

I am new to PHP and CakePHP, so any advice you can give is appreciated.

Update:

So instead of the example URL above, it has been URL-escaped to look like this:

http://example.com/redirector/1/http%3A%2F%2Fwww.google.com

However, my routing is still not working. Here's what I have in routes.php:

Router::connect(
	'/redirector/:id/:url',
	array('controller' => 'redirects', 'action' => 'myredirectaction'),
	array(
		'id' => '[0-9]+',
		'url' => 'http.*'
	)
);

This is what I get when I try that URL:

And more warnings from my action since it did not get the two expected arguments.

Of course, I've changed my action to urldecode($url) before using the $url.
