Thanks.

Using the two ProxyPass directives per above sends a request into a loop.

That includes removing the /frontpage from the BalancerMember declarations:

<Proxy balancer://applicationcluster>

                BalancerMember https://app1.example.com:8443
<https://app1.example.com:8443/frontpage> route=node1
                BalancerMember https://app2.example.com:8443
<https://app2.example.com:8443/frontpage> route=node2
                BalancerMember https://app3.example.com:8443
<https://app3.example.com:8443/frontpage> route=node3
                ProxySet lbmethod=bybusyness

</Proxy>

ProxyPreserveHost       On
ProxyPass / balancer://applicationcluster/frontpage/
stickysession=JSESSIONID
ProxyPass /frontpage/ balancer://applicationcluster/frontpage/
stickysession=JSESSIONID
ProxyPassReverse / balancer://applicationcluster/frontpage/
stickysession=JSESSIONID

Well, so far the only option that has been partially successful for me is
to use a rewrite.  As mentioned, If I use:

RewriteEngine   On
RewriteRule "^/frontpage(.+)" "$1" [R,L]

^^^^
This allows for the login page to load successfully but subsequent requests
fail.

Any thoughts on a URL rewrite(s) that might work?  I've played around with
%{REQUEST_URI} and IS_SUBREQ but have had not success so far..

Any suggestions are very welcome..
