Abstract
In one embodiment of the present invention, a messaging program at a remote computer can send a first message to a portal computer according to a one-way protocol such as HTTP. A portal program at the portal computer can receive the first message and determine if information should be sent to the portal computer. If so, the portal computer can generate a reply message that includes the information and send the reply message to remote computer on the same connection over which the first message was received. In this manner, the portal computer can send configuration control information and other information to the messaging program without requiring leased lines, dial-up connections or a VPN. Moreover, since the communication according to the one-way protocol was initiated at the remote computer, a firewall will allow the remote computer to receive the reply message.
