Here is the Apache Reverse proxy and load balancer, the website/reports url is not coming up

   <IfModule mod_proxy.c>
        ProxyPreserveHost On
        <Proxy balancer://app0102>
           BalancerMember https://serverapp01.com
           BalancerMember https://serverapp02.com
        </Proxy>
        ProxyPass / "balancer://app0102/"
        ProxyPassReverse "/" "balancer://app0102/"
   </IfModule>

if I point to single server, the website/reports url work

<VirtualHost *:443>
   <IfModule mod_proxy.c>
      ProxyPass / https://serverapp01.com

/ retry=1 acquire=3000 timeout=1200 Keepalive=On
ProxyPassReverse / https://serverapp01.com

Website works in both cases, Any ideas on what I am missing
Thanks
Nate

  1. If your backend server is using SessionCookie then you can use the same cookie for sticky session.

    <Proxy balancer://app0102>
    BalancerMember https://serverapp01.com route=node1 
    BalancerMember https://serverapp02.com route=node2 
    </Proxy>
    
    ProxyTimeout 60
    ProxyStatus On
    
    ProxyPass /   balancer://app0102/  stickysession=JSESSIONID|jsessionid 
    ProxyPassReverse / bbalancer://app0102
    

    If your backend server is not using Session Cookie then you can use route for sticky session.

    Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e;  path=/" env=BALANCER_ROUTE_CHANGED
    <Proxy "balancer://app0102">
        BalancerMember https://serverapp01.com route=node1
        BalancerMember https://serverapp02.com route=node2
        ProxySet stickysession=ROUTEID
    </Proxy>
    ProxyPass / balancer://app0102/
    ProxyPassReverse / balancer://app0102/
    
    

    Make sure that your both backend server is running.

  2. I suggest using quotes on both source and destionation,
    such as:

    ProxyPass “/” “balancer://app0102/”
