Pass url parts as array to controller

[eluser]Unknown[/eluser]
Best,

I was wondering if it is possible to pass the whole url in array form to the called controller method.

so for example if I call

Code:

/controller/action/param1/param2/param3

I don't wish to catch those by creating

Code:

public function action($param1, $param2, $param3)

But rather

Code:

public function action($params)

This because I do not know in advance how many parameters will be passed through.

Thanks!
Pj
