Abstract
In an E-commerce method for selling digital content over the Internet an FTP-like protocol is provided to carry out the delivery (download) of a purchased digital content item from a server computer to a client computer operated by the purchaser. The FTP-like communication protocol provides for error recovery during the download that does not require restarting the download from the beginning. After the download is completed the integrity of the downloaded file is checked. And the result of the check is communicated to the server which records that the digital content item has been successfully delivered to the purchaser.
