DO NOT REPLY [Bug 48219] New: Retrying the worker for seems to omit POST variables

https://issues.apache.org/bugzilla/show_bug.cgi?id=48219

           Summary: Retrying the worker for seems to omit POST variables
           Product: Apache httpd-2
           Version: 2.2.3
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mod_proxy_balancer
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: ops@tyro.com


It appears that when mod_proxy_balancer is retrying to sent a request to the
same worker it drops the POST data and adds itself again to the relevant
x-forwarded headers:


first request (has been modified for security reasons):
[18 Nov 2009 12:16:30,683]
POST /integration-server/terminals/2/103/transactions HTTP/1.0
Host: a.tyro.com
User-Agent: changed
Accept: */*
Content-Type: application/x-www-form-urlencoded
Expect: 100-continue
X-Forwarded-For: A.B.C.D
X-Forwarded-Host: a.tyro.com
X-Forwarded-Server: a.tyro.com
Content-Length: 154


second request (has been modified for security reasons):
[18 Nov 2009 12:16:30,690]
POST /integration-server/terminals/2/103/transactions HTTP/1.0
Host: a.tyro.com
User-Agent: changed
Accept: */*
Content-Type: application/x-www-form-urlencoded
Expect: 100-continue
X-Forwarded-For: 59.167.235.179, 59.167.235.179
X-Forwarded-Host: a.tyro.com, a.tyro.com
X-Forwarded-Server: a.tyro.com, a.tyro.com
Content-Length: 0

This is a reproducible behaviour. Does that make sense to anyone who knows the
code? 

Also just to confuse me a little bit more: Our application servers responded
with a 503 and it looked like the balancer is retrying the connection instead
of passing this on to the client? I did some reading and thought that the
balancer only considers a connection problem to the worker a failover reason?

Our configuration is:
[...] 
  SetEnv          force-proxy-request-1.0        1
        SetEnv          proxy-nokeepalive              1
        <Proxy balancer://integrationwebapp>
                BalancerMember http://webapp-1:8008 retry=60
                BalancerMember http://webapp-2:8008 status=+H
                ProxySet lbmethod=bytraffic
        </Proxy> 
[...]
