Abstract: Computer implemented methods and apparatus for determining availability information for a first one of a plurality of products for publication via a wide area network. The availability information is calculated with reference to a delivery date, an available number of units, and a reserved number of units, the delivery date having been specified by a user via the network, the available number of units having been determined with reference to inventory information, and the reserved number of units having been determined with reference to current order information.

Abstract: A technique is disclosed for generating formatted information for display on a computer system. The computer system may be configured to include at least one interface for communicating with a server computer system. A request is sent from the computer system to the server system. According to one embodiment, the request may correspond to an HTTP request for information relating to a specific HTML page or web page. A response is then received from the server system. According to one embodiment, the response includes response information comprising embedded instructions and data. The embedded instructions may include instructions for using the data to generate formatted markup information for display on the computer system. The embedded instructions are then executed on the data to thereby generate formatted markup information for display on the computer system. According to a specific embodiment, the formatted markup information corresponds to HTML data to be rendered for display on the computer system.

Abstract: A technique for effecting electronic commerce using a data network is described. The data network includes a plurality of subsystems which, together, form an integrated system for receiving customer orders for selected items via a data network, fulfilling the customer orders, and delivering the ordered products to the customers. Moreover, according to a specific embodiment, the integrated nature of the system architecture of the present invention allows the on-line merchant to provide a guarantee to the customer that the ordered items will be available to be delivered to the customer at the specified delivery date, time, and location.

Abstract: Techniques for implementing a load balanced server system are described which may be used for effecting electronic commerce over a data network. The system comprises a load balancing system and a plurality of servers in communication with the load balancing system. Each of the plurality of servers may include a respective data cache for storing state information relating to client session transactions conducted between the server and a particular client. The load balancing system can be configured to select, using a load balancing protocol, an available first server from the plurality of servers to process an initial packet received from a source device such as, for example, a client machine of a customer. The load balancing system can also configured to route subsequent packets received from the source device to the first server. Before generating its response, the first server may verify that the state information relating to a specific client session stored in the data cache is up-to-date.
