Hi Alisha,
You would need to use proxy plugin module (mod_proxy) to redirect the request to backend application server.
The ProxyPass directive specifies the mapping of incoming requests to the backend server (or a cluster of servers known as a Balancer group). The simpliest example proxies all requests ("/") to a single backend:
ProxyPass "/" "http://www.example.com/"
To ensure that and Location: headers generated from the backend are modified to point to the reverse proxy, instead of back to itself, the ProxyPassReverse directive is most often required:
ProxyPass "/" "http://www.example.com/"
ProxyPassReverse "/" "http://www.example.com/"
Only specific URIs can be proxied, as shown in this example:
ProxyPass "/images" "http://www.example.com/"
ProxyPassReverse "/images" "http://www.example.com/"
In the above, any requests which start with the /images path with be proxied to the specified backend, otherwise it will be handled locally.
Refer below link for more details.

Also can siteminder reverse proxy work with two load balancers. ?
Are you talking about CA Access Gateway ? if so, yes you can use CA Access gateway under load balancer and Also you can use it as proxy server for redirecting to backend appliction server.
Thanks,
Sharan
