This method is commonly used to POST the redirect url during cart finalization to prevent the user from hitting the back button (so easily).
Here is a code snippet from a checkout() button implementation.

    ultraCart.saveFieldElements(function (){
      ultraCart.checkout(checkoutMethod || ultraCart.checkouts.CHECKOUT_ULTRACART, {async:true, onComplete:function(result){
        if(result.redirectToUrl){
          ultraCart.util.postGet(result.redirectToUrl); // post instead of redirect to discourage back button use.
        } else if(result.errors) {
          finalizing = false;
          renderErrors(result.errors);
        } else {
          finalizing = false;
          // ?? this should never happen.
        }
      }})
    });
