Answer : A/ B/ D/

A is correct : The proxy plug-ins are intelligent enough to stick the request from a client to the same server where the session is hosted
Source : http://weblogicserver.blogspot.fr/2009/08/weblogic-server-http-session-failover.html

B is correct : The proxy server will randomly distribute all the requests from the failed server to different servers that are still running in the cluster.

C is wrong

D is correct : Using the AutoFill Function

You can easily add valid WebLogic Server and endpoint locations for a specified Base UIRL to the Locations table on the WebLogic Proxy Plug-In Configuration screen by using the AutoFill button. To do so:
Click Add to add a new location,
Type a location name in the Location field.
Click AutoFill.
Data for any location of the same name will be updated and any new locations will be added to the table.

F is wrong : In the case of two-way SSL, the plug-in (the SSL client) automatically uses two-way SSL when Oracle WebLogic Server is configured for two-way SSL and requests a client certificate

E is wrong : the object and its attributes are replicated in a cluster using in-memory replication. If you use other set methods to change objects within a session, WebLogic Server does not replicate those changes. Every time a change is made to an object that is in the session, setAttribute() should be called to update that object across the cluster.
