problems with weblogic HTTPProxy Plugin(Round robin not
happening)

Hi,

I have a cluster of two servers.
Machine 1:
Admin Sever and Managed Server1
Machine2:
Managed Server2
Machine 3:
Weblogic Porxy plugin

So my Manged Server1 and 2 are in cluster and I am using Weblogic Porxy plugin
for load balancing. But whenever I am triggering appplication, all my Request
goes to MangedServer1 only and when Managed Server1 goes down then only the
request goes to Server2. Even i tried from different machines with different
sessions. So the round robin thing is not working here. I have deployed the
sampled application of [b]InMemRep[/b] that comes with weblogic. 
Any pointers on this will really be appreciated and it will be a great help
