Health Check is not working, always shows a node up.

[Vladimir L <vliapko@xxxxxxxxx>]

I am testing with 3backend nodes, 1st returns 404, the third is not responding at all, but Apache seems never tries to send a health check there. All nodes are shown Init OK in Balancer Manager all the time. Apache 2.4.23 RHEL

ProxyHCExpr ok234 {%{REQUEST_STATUS} =~ /^[23]/}
