Can someone help me. I am trying to test the communication between ISs having a VIP in between. So, I have a client package on IS A, and the server package on 4 different ISs. The VIP is “dm3.eai”. The problem I have is that all the requests are going to the same server though the VIP is configured to serve the requests in round robin fashion. Where as when I tried to send requests from the normal java webservice client, the VIP passes the requests to the servers in round robin fashion. I don’t know what the difference is, however I presume there is a session maintained in the client IS A. Any idea what the problem is ? Your help is much appreciated.
