Failover scenario is not performed with httpd balancer - balancer fails to respond

      1. Prepare configuration with one balancer (Apache 2.4.29) and workers (Wildfly/EAP)
      2. Send request to balancer and obtain JSESSIONID (e.g. 54yxdncGr5im0fBLqIIUMon0klbS66X16aYC_cVW.jboss-eap-7.2-3)
      3. Kill worker which handled the request
      4. Make another request with same JSESSIONID

      When second request in failover scenario is made to check whether the failover was done, server fails to respond. With Undertow as a balancer, this behavior cannot be reproduced. When I replace the jvmroute part by worker which is still alive, I got expected response.
