Server ID

When the server is created, WebSphere assigns a unique CloneID for each server, the cloneID is shown in the plugin-cfg.xml file:

    <ServerCluster Name="HACluster">

        <Server CloneID="u307p2vq" LoadBalanceWeight="2" 
Name="HAClusterServer1"></Server>

        <Server CloneID="u307p48r" LoadBalanceWeight="3" 
Name="HAClusterServer2"></Server>

        <Server CloneID="u307p62u" LoadBalanceWeight="4" 
Name="HAClusterServer3"></Server>

        <Server CloneID="u307p71m" LoadBalanceWeight="5" 
Name="HAClusterServer4"></Server>

    </ServerCluster>

The CloneID is used to create the serverGroup object. The plug-in will bind the CloneID and a client's sessionID when it receives the client's first request as shown in Example 9-7.
