Hey All, we have apache2 2.4.54 setup as a load balancer for our IIS backend servers. We would like to be able to carry out health checks using mod_proxy_hcheck and check that the backend server is serving a webpage. We have successfully set this up however in the event that a health check request to the backend hangs, apache never reaches a timeout and therefore the healthcheck doesn't fail.
We have found a commit https://github.com/apache/httpd/commit/ab2b9dbfb74049ad207a91c45971948127dde893 that fixes this issue, we have verified this by building apache with this change applied and confirmed that when a timeout is provided in the apache balancer configuration, specifically on the BalancerMember line, the healthcheck(s) will timeout and put the backend into a failed state. This code is not in the latest apache release, does anyone have any idea if this will be part of a future release? Or can advise regarding this issue.
