Description hihellobolke 2021-09-10 00:39:28 UTC
When using configuration like below

```

ProxyHCExpr ok234 {%{REQUEST_STATUS} =~ /^[234]/}
<Proxy balancer://myset>
  BalancerMember http://be-1:8081 hcmethod=GET hcexpr=ok234 hcinterval=3 hcpasses=3 hcfails=1
  BalancerMember http://be-2:8081 hcmethod=GET hcexpr=ok234 hcinterval=3 hcpasses=3 hcfails=1
  BalancerMember http://be-3:8081 hcmethod=GET hcexpr=ok234 hcinterval=3 hcpasses=3 hcfails=1
  ProxySet lbmethod=bytraffic
</Proxy>

```

Apache health check sends request with path as "" as below

```
GET  HTTP/1.0
Host: be-1:8081
```

This returns a Bad request, apache should default path to "/"
