Failover in two separate weblogic clusters in apache config

Got through a post here :

http://stackoverflow.com/questions/12932055/how-to-configure-weblogic-plugin-in-apache-for-the-same-location-for-different-c

The person wants to add two separate cluster URLs in apache as follows:

  <Location /service>
     WebLogicCluster 10.0.0.1:7045,10.0.0.2:7045,10.0.0.3:7045,10.0.0.4:7045
     SetHandler weblogic-handler
  </Location>
If done it will have following consequences:

• Requests will follow session stickiness for each member in cluster
• On failure it will assume that any other member in cluster is a valid failover target
• it might go to member which is part of different cluster and hence user state will not be in that cluster so request will fail

so the question is what if you have two different domains with different clusters and same application deployed in those separate vertical clusters how will you configure same URL to be forwared separately to different clusters ?
