I'm developing an ajax request handling extension of the default cart controller. How do I find out the correct URL to use in order to send information back to the server?
the controller (CartController.php) class definition is:
require_once 'Mage/Checkout/controllers/CartController.php';
class CompanyName_Checkout_CartController extends Mage_Checkout_CartController{
function couponPostAction(){
}
}
the config.xml will look something like:
<frontend>
<routers>
<checkout>
<args>
<modules>
<companyname_checkout before="Mage_Checkout">Companyname_checkout</companyname_checkout>
</modules>
</args>
</checkout>
</routers>
</frontend>
Assuming the above is correctly configured... what will be the resultant URL I will use to reach this controller?
