route question

[eluser]Unknown[/eluser]
Is it possible to do this:

Code:

$route['product/:any'] = "catalog/product_lookup";

From the user guide, it says that doing that will have any url that is product/anything will be sent to catalog/product_lookup

I'm wondering how it is possible to get that :any as a variable in the document. Is it done with the uri segment thing? If so, how?

Thanks.

EDIT: Would it be done like this:

Code:

$product_id = $this->uri->segment(2);

then $product_id would equal :any?

(If this is really simple, sorry, I'm new to using CI.)
