Doc Text:
Previously, when the ProxyErrorOverride directive was enabled, the mod_cluster load balancer returned the 503 status code on subsequent requests for about one second. This caused failover, which then propagated through the instances. Additionaly, this bug could be used for the denial of service (DoS) attack. With this update, the requests in the described scenario are now handled correctly with the 200 status code.
