Hi, this is another example using location directive for balancing applications
arounds tomcats:
suppose that you have 3 urls or applications you want to balance using these
context path: app1, app2 and app3
suppose that you have 2 tomcats with ajp on ports 8009 and 8007
so you config is:
<Proxy balancer://tomcats/>
BalancerMember ajp://tomcat-srv1.com:8007 route=tomcat1 loadfactor=1
keepalive=On
BalancerMember ajp://tomcat-srv2.com:8009 route=tomcat2 loadfactor=1
keepalive=On
</Proxy>
<Location /tomcats/app1/>
ProxyPass balancer://tomcats/app1/ stickysession=jssesionid|JSESSIONID
nofailover=On lbmethod=byrequests
ProxyPassReverse balancer://tomcats/app1/
Order Deny,Allow
Allow from all
</Location>
<Location /tomcats/app2/>
ProxyPass balancer://tomcats/app2/ stickysession=jssesionid|JSESSIONID
nofailover=On lbmethod=byrequests
ProxyPassReverse balancer://tomcats/app2/
Order Deny,Allow
Allow from all
</Location>
<Location /tomcats/app3/>
ProxyPass balancer://tomcats/app3/ stickysession=jssesionid|JSESSIONID
nofailover=On lbmethod=byrequests
ProxyPassReverse balancer://tomcats/app3/
Order Deny,Allow
Allow from all
</Location>
and to monitor your balancer
<Location /balancer-manager>
SetHandler balancer-manager
AuthType Basic
AuthName "Cluster manager "
AuthUserFile conf/.htpasswd
Require valid-user
Order Deny,Allow
Allow from all
</Location>
do not forget to add proxy modules
Inas.
