The request is received from PayPal. Related information...this same
listener script a) receives data from PayPal, b) sends data back top
PayPal, then c) receives validation from PayPal (or not, depending). The
script is successfully causing the data received from PayPal to be
written to a MySQL database. So the script is executing.
