Abstract
A device, system, and method for maintaining session persistency between one or more clients and one or more data servers includes providing a persistent session between the client(s) and data server(s) as a function of a load balancer hint header included in a message received by the load balancer from the client(s). The client(s) modifies the message, which may be generated by an application, to include the load balancer hint header that identifies a location, within the message, of a session ID that identifies the particular persistent session. The load balancer identifies the data server(s) from a session-server table based on the session ID and transmits the message to the identified data server(s). The load balancer may communicate with other load balancers, if the load balancer is unable to locate the corresponding data server, to determine the location of the corresponding data server(s).
