We use mod_proxy to distribute requests to four tomcat instances.
Our configuration (vhost.conf) is as follows:
<VirtualHost aa.bb.cc:3000>
ProxyPass /balancer-manager !
ProxyPass / balancer://mybalancer/ stickysession=JSESSIONID
<Proxy balancer://mybalancer>
BalancerMember ajp://xx.yy.zz:11009/ldsportal route=tomcat1
loadfactor=50
BalancerMember ajp://xx.yy.zz:12009/ldsportal route=tomcat2
loadfactor=50
BalancerMember ajp://xx.yy.zz:13009/ldsportal route=tomcat3
loadfactor=50
BalancerMember ajp://xx.yy.zz:13009/ldsportal route=tomcat4
loadfactor=50
</Proxy>
<Location /balancer-manager>
SetHandler balancer-manager
</Location>
</VirtualHost>
Things work fine this way, but occasionally, we have to shut down a single
instance for maintenance.
We use the balancer manager to reconfigure the respective worker (say: tomcat1)
to redirect to another worker:
- select the instance tomcat1 from the web GUI
http://aa.bb.cc:3000/balancer-manager
- enter e.g. tomcat2 in the "Route Redirect" form field.
- on submit, the respective worker is marked with "RouteRedir=tomcat2" in the
worker list.
Our problem is, requests without a session id still get routed to worker
tomcat1 (as well as to the other 3 instances).
We use [Server Version: Apache/2.2.3 (Linux/SUSE)] in our production env, but I
also tried [Server Version: Apache/2.2.11 (Win32)]
The result is the same in both setups.
Am I missing something essential?
Cheers
