Applications

In most e-commerce application systems or online systems requiring subscriber identity authentication, several interactions are conducted between the customer and the server to complete a transaction or a request. These interactions are closely related. The server often needs to know the processing result of the last one or several interactions when performing a certain interaction step. When the server performs the next step, it requires that all these related interaction processes should be completed by one server, instead of being distributed to different servers by the load balancer. In this case, the corresponding session persistence policy is used to ensure that related requests are delivered to the same backend server.
