Requirements for Load Balancer
Passive Cookie Persistence
Passive cookie persistence enables WebLogic Server to write a cookie containing
session parameter information through the load balancer to the client.
Active Cookie Persistence
Certain active cookie persistence mechanisms can be used with WebLogic Server
clusters, provided the load balancer does not modify the WebLogic Server cookie.
SSL Persistence
When SSL persistence is used, the load balancer performs all encryption and decryption
of data between clients and the WebLogic Server cluster. The load balancer then uses
the plain text cookie that WebLogic Server inserts on the client to maintain an
association between the client and a particular server in the cluster.
