This step is completely optional, and only required if you have access to an SSL server, and want to make sure all orders are placed on the SSL server. To do this, you need to move the order.cgi script on your server. FTP into your server, and change to the /cgi-bin/xflow/modules/shop/bin/ directory on your server. You will see an order.cgi script in this directory, which you can download, then re-upload to your SSL server. Please make note of the URL of the order.cgi script after you've moved, as it's required during First Time Setup.
