The problem i was having was that despite the fact i only specified 2 of the 6
the managed servers in my cluster in the config file it would end up finding the
other 4 from the cluster and start routing requests to those. Which due the
differences in geographical location is was not what we wanted. This happens
because after the first request the cluster responds with a "Dynamic Server
List" which the cluster constantly updates after each request and it
contains a list of all the "UP" server in the cluster. This is how the
HttpClusterServlet was learning of the other 4 machines. 

The solution was to use the weblogic plugin with apache etc and use apache as
the proxy / balancer. In the plugin configuration you can specify to disable the
Dynamic Server List with the parameters "DynamicServerList  OFF". This
mean the instance of apache only ever tries to communicate with the servers you
specify in the weblogiccluster parameter and it ignores the Dynam
