add the following code to the shipping failure page so i can see the full request being sent and the full response returned by USPS:
<?php
@session_start();
echo "<p>USPS: <br />";
echo "Full Request: ".(isset($_SESSION["afgcart_USPS_FullRequest"])?htmlentities($_SESSION["afgcart_USPS_FullRequest"]):"n/a")."<br />";
echo "Full Response: ".(isset($_SESSION["afgcart_USPS_FullResponse"])?htmlentities($_SESSION["afgcart_USPS_FullResponse"]):"n/a")."<br /></p>";
?>
