Abstract
A technique for implementing a load balanced server farm system is 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 is 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 is also configured to route subsequent packets received from the source device to the first server. In this way, a “stickiness” scheme may be implemented in the server farm system whereby, once an electronic commerce session has been initiated between the first server and the source device, the first server may handle all subsequent requests from the source device in order to make optimal use of the state data stored in the first server's data cache.
