Hello,
I don't have an F5 example but I have customers that successfully use a load balancer (Avi, if that makes a difference) for OneClick and Webapp. For the most part, they followed what was listed here:
To achieve load balancing, identically configured OneClick web servers are accessed through an external load balancing device that employs host/session persistence and any load-balancing mode.
Check OneClick Web Server Status
You can configure your load balancer to check the status of each OneClick server by using the following HTTP GET statement during periodic server health checks:
http://<hostname>:<portnumber>/spectrum/stable
A successful GET returns the contents of the "stable" file. The presence of the stable file indicates that the SpectrumTomcat process is in a stable state. Failure to retrieve the file indicates that the SpectrumTomcat process is not running or is unstable.
They're using the stable check for both the regular Tomcat and WebTomcat configuration, ports 8443 and 9443 respectively. That does leave the possibility that WebTomcat could be having an issue while Tomcat is fine so we're looking to configure an additional health check specifically for WebTomcat.

you ever get this working. I'm lost with this and my load balancer team is even more lost.

Recently upgraded from 10.3.1 to 10.4 and have got problems with my F5 loadbalancer setup in front of both tomcat and webtomcat.
Onelick Java (oneclick.jnlp)
Before upgrade urls in client session was dynamic. Users accessed https://spectrum.x.x and and the loadbalancera forwarded the session to vlpspec001 or vlpspec001. All communication worked as the jnlp file contained dynamic urls (https://spectrum.x.x). But in 10.4 the downloaded onclick.jnlp contain static url's that point to either of the two answering oneclick servers, which the client do not have access to - so communication can't continue.
OnclickWebApp (tomcat & webtomcat)
In 10.3.1, you could access the oneclickwebapp directly on port 9443 (if configured), which worked fine. But in 10.3.2/10.4 there is a new way to setup the client session. When clicking the oneclickwebapp url a new browser opens which download index.jsp from the tomcat, which instructs the browser to wait for data from the webtomcat. So there is two different tomcats involved and the webtomcat session isn't established from the client. The loadbalancer therefor can't connect the server dataflow with the client.
Anyoneelse haveing a loadbalancer in front on oneclick/webapponeclick and got it working ?

P.s. Everything is working inside firewalls without loadbalancing. I have created to tickets on this, but support/SE seems to be very slow in understanding the problem - as its working without loadbalancing :(</portnumber></hostname></dick.baker@nttdata.com></mail@connectedcommunity.org></nitish11.mishra@nttdata.com></brian.flad@broadcom.com></dick.baker@nttdata.com></nitish11.mishra@nttdata.com>
