I have a possible solution but am not 100% satisfied with it. This seems to work with httpshttpd version 2.2.22.
ProxyRequests Off ProxyPreserveHost On <Proxy balancer://mycluster> BalancerMember http://localhost:8080 </Proxy> ProxyPass / balancer://mycluster/ maxattempts=1000 ProxyPassReverse / balancher://mycluster/ The balancer parameter maxattempts sets the number of attempts that the balancer will use while cycling through balancer members and sending them requests while they fail. I'd rather have a solution with a timeout but I haven't found anything that worked other than maxattempts.
