I have a Joomla 3 website using virtuemart 3. I notice in the cart page the url is domain/cart. Then on the payment page the same url is repeated (domain/cart). And once again in the thank-you-page the same url is used once more (domain/cart). I am wondering what is the best approach towards creating more semantic urls for the two latter pages? (i.e. domain/cart for cart, domain/payment for payment, and domain/thank-you for the thank-you page)
