| Hosts / Host Technical Reference | |
Use generic AS3 Hosts to specify an AS3 installation based on a specific AS3/FTP server product.
This includes the product's specific server choreography, or the commands needed to successfully log in to the remote server and send and receive files. The product choreography for each generic AS3 host was established during AS3 interoperability testing with the server products, and a generic host for all interoperability-certified AS3 products is included in the VersaLex installation. Since these hosts were created for a test environment, you might need to adjust some settings and commands to establish successful file transfers in a production environment. If it is available, use a pre-configured host specific to your trading partner's remote server. This makes for a faster and easier set up of your installation.
The AS3 standard provides the ability to securely transport EDI (and other data, including binary and XML) to a remote host over FTP, guaranteeing that the message has not been changed in-transit and has been received and can be read only by the intended trading partner. An Message Disposition Notification (MDN) receipt further guarantees that the intended trading partner has received the message.
AS3 uses the FTP protocol as its transport mechanism to send and receive files over the Internet. VersaLex uses the PUT/GET action commands to transport the secure data to/from the remote host.
