I have configuration of Apache+modcluster and two JBOSS AS7 (AS1 + AS2).

Here Apache+modcluster and AS1is on same node and AS2 is on another node.

It is also possible to add another JBOSS AS7 (AS3 ) dynamically in cluster .

In this case  load balancing  work properly for all HTTP request.

Consider that URL1 is some special URL.

When URL1  come to  Apache+modcluster it must forward to AS1 only .

If AS1 fail then only URL1 should  forward to other  ApplicationServer in  cluster.

How to configure Apache+modcluster to solve this problem?
