Description of problem:

When I set up a balancing reverse proxy with sticky sessions, the Proxy definitions need to be inside the virtualhost definition, otherwise the balancers parameters do not work.


Version-Release number of selected component (if applicable):

httpd-2.4.6-40.el7.x86_64

How reproducible:
All the time

Steps to Reproduce:
1. Create a balancer and vhost in /etc/httpd/conf.d/balancer.conf

LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"\n- BALANCER_SESSION_STICKY: \"%{BALANCER_SESSION_STICKY}e\"\n- BALANCER_SESSION_ROUTE: \"%{BALANCER_SESSION_ROUTE}e\"\n- BALANCER_WORKER_ROUTE: \"%{BALANCER_WORKER_ROUTE}e\"\n- BALANCER_ROUTE_CHANGED: %{BALANCER_ROUTE_CHANGED}e\n- Set-Cookie: %{Set-Cookie}o\n- JSESSIONID cookie: %{JSESSIONID}C" DebugBalancer

<VirtualHost 0.0.0.0:80>
  ServerName test
  DocumentRoot "/var/www/html"
  <Directory "/var/www/html">
    AllowOverride None
    Require all granted
  </Directory>
  ErrorLog "/var/log/httpd/test_nossl_error.log"
  LogLevel debug
  ServerSignature Off
  CustomLog "/var/log/httpd/test_nossl_access.log" "DebugBalancer" 
  ProxyRequests Off
  ProxyPreserveHost Off
  ProxyPass /test balancer://test-nbi/test scolonpathdelim=On stickysession=JSESSIONID|JSESSIONID
  ProxyPassReverse /test http://10.60.0.111:8082/test
  ProxyPassReverse /test http://10.60.0.112:8182/test
  ProxyPassReverse /test http://10.60.0.113:8282/test
</VirtualHost>
<Proxy balancer://test-nbi>
 BalancerMember http://10.60.0.111:8082 route=fna080-test-interface-1
 BalancerMember http://10.60.0.113:8282 route=fna080-test-interface-3
 BalancerMember http://10.60.0.112:8182 route=fna080-test-interface-2
</Proxy>


2. Put something behind 10.60.0.112:8182 10.60.0.113:8282 10.60.0.111:8082 which sets a JSESSIONID cookie
3. Open the browser to the virtualhost, refresh multiple time

Actual results:

In the logs:
10.110.254.5 - - [03/Mar/2016:11:09:40 +0100] "GET /test/login HTTP/1.1" 200 20836 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:42.0) Gecko/20100101 Firefox/42.0"

- JSESSIONID cookie: fna080-test-interface-32muoaee8ywiw18dlwwi4o117w.fna080-test-interface-3


In the browser:
The requests are not served by the same backend

Expected results:

- Set-Cookie: -
- JSESSIONID cookie: fna080-test-interface-3x57xw5y2jqas1am4662xfxrbk.fna080-test-interface-3

In the browser:
The requests are served by the same backend

Additional info:

Puttinq the <Proxy> block inside the <Virtualhost> block fixes the problem. However if this would be a configuration error from my side, I expect the virtualhost not to be able to use the balancer at all, instead of being able to use it but not able to set parameters.
