 * "Revises [st10GetOrder] to allow the user to order with 
 * a POST request as well as a GET request"
 * 
 * (one advantage: "browser does not include the data with the POST request.
 * Thus using POST instead of GET is essential to keep the data sent private.
 * Data sent with a GET request is appended to the URL and displayed in the
 * browser's address field.")
