Abstract
A shared session cache can be accessible by multiple load balancers, and can indicate whether client devices are associated with specific backend servers of a server pool. When a client device connects to a load balancer, the load balancer can use the shared session cache to determine if the client device is already associated with a specific backend server. If so, the load balancer can connect the client device to that specific backend server so that it can continue an existing session with the specific backend server. If not, the load balancer can select a new backend server for the client device, connect the client device to the newly selected backend server, and create an entry in the shared session cache indicating that the client device is associated with the newly selected backend server.
