AS2 provides an Internet solution for securely EXCHANGING EDI over the Internet using MULTIPURPOSE Internet Mail Extensions (MIME) and the hypertext transmission protocol (HTTP) instead of the simple mail transport protocol (SMTP) as the transport protocol. AS2 specifies the means to connect, deliver, validate, and reply to (receipt) data in a secure and reliable way. AS2 does not concern itself with the content of the EDI document, only the transport.

AS2 essentially creates a WRAPPER around EDI flat FILES that enables sending them over the Internet, instead of using a dial-up connection to a value-added network (VAN). AS2 is a real-time technology that provides security and encryption around the HTTP packets.
