Subject: Apache Http Server Load Balancing and Failover

I have Apache Http Server v2.2.3 configured as a reverse proxy with load
balancing to a WADI clustered application on Geronimo 2.1.5.  Load balancin=
g
and failover works fine if one of the Geronimo instances fail.  However, if
only the application fails or is stopped I get a 404 error and failover doe=
s
not work?=20

Here=E2=80=99s the LB config:

<IfModule mod_proxy_balancer.c>
     <Proxy balancer://wadicluster>
           Order deny,allow=20
           Allow from all=20
         BalancerMember ajp://localhost:8209/NodeDetection loadfactor=3D50
route=3Dnode1=20
         BalancerMember ajp://localhost:8409/NodeDetection loadfactor=3D50
route=3Dnode2=20
     </Proxy>=20
     ProxyPass /NodeDetect balancer://wadicluster  stickysession=3DJSESSION=
ID
=09=09
     ProxyPassReverse /NodeDetect ajp://localhost:8209/NodeDetect
     ProxyPassReverse /NodeDetect ajp://localhost:8409/NodeDetect

    <Location /balancer-manager>
         SetHandler balancer-manager
         Order Deny,Allow
         Allow from all=09=09=09
    </Location>=20

</IfModule>=09=09

I need to make this work with an application failure as well as a server
failure.  Any ideas?  Thanks.
