Downloadable Digital Product Delivery
File downloads may be provided when products are ordered through the shopping cart.
Product file downloads are controlled by the software, which protects the files against unauthorized access.
When downloadable products are ordered the receipt
includes a link and password for customers to download product files.
There is also an option to automatically log customers into the
download page after payment is completed (not supported
by all payment gateways).
