Error description
Problems when session cookie name is renamed from its default
value. Session Affinity is failing because the session
cookie name is being modified on the session manager and since
the plugin by default does not recognise the changed name, it
uses its WLM algorithm to route the requests to the different
clones. The plugin code has already been fixed to recognise a
different cookie name by reading in a property
which can be provided manually in the queues.properties file. An
internal defect 119922 was opened to make the servlet engine
generate this property for each queue if it needs to.
.
This apar is for internal defect 119922.

****************************************************************
The plugin uses the cookie provided on the session manager to
establish and maintain session affinity.  The plugin by default
looks for a cookie by name 'sesessionid' to get the cookie
value.  So if the cookie name is modified on the session manager
the plugin would not be able to detect the name change unless
the new cookie was provided to it for that particular model.
Problem conclusion
This fix causes the servlet engine to generate the
queues.properties file with a property which specifies the
cookie name for each model containing more than one clone
therefore enabling the plugin to maintain session affinity.
