Dynamically Adding BalancerMembers to Proxy

Question

Running Apache 2.4 I would like to be able to dynamically add BalanaceMembers via API to a balancer group in the proxy_balancer module.

There are hints that this is possible. The documentation for mod_proxy_express says mod_proxy_balancer "provides dynamic growth."

I see that there is a BalancerGrowth directive, which I have tried adding but see no more slots in the balancer-manager page.

How do I provide for dynamic growth of proxy balancer members? How do I add and remove them? Where is the documentation for the API for adding, removing, and managing members?

this does not yet work for me because i do not see something in the user-interface how i would add it but maybe this helps you. i will give you an update if i find out something new

i used the configuration option mentioned in this thread

<Proxy balancer://myset growth=5>
    BalancerMember http://localhost:8080 route=8080
    BalancerMember http://localhost:8081 route=8081
    ProxySet lbmethod=bybusyness
    ProxySet stickysession=JSESSIONID 
</Proxy>

EDIT

if you click on the lb-link there is a new input field and a checkbox. here you can add new workers. i don't know if one can remove them though. maybe just disabling hosts is possible
