LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
<IfDefine SSL>

<VirtualHost _default_:443>
<Proxy balancer://tomcatservers>
BalancerMember ajp://server_name:8009 route=tomcat4 retry=60
BalancerMember ajp://server_name:8010 route=tomcat5 retry=60
</Proxy>
<Location /*>
Allow From All
ProxyPass balancer://tomcatservers/* stickysession=JSESSIONID nofailover=off
</Location>
and tomcat server.xml contain following entry.
Tomcat5
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat5">

Don't use the wildcards:
<Location />
Allow From All
ProxyPass balancer://tomcatservers stickysession=JSESSIONID
nofailover=off
</Location>
Or use the simpler
ProxyPass / balancer://tomcatservers stickysession=JSESSIONID nofailover=off

Hello Eric,
I have tested my virtual host configuration using command apachectl -S and it's saying syntax OK.
bash-3.00# ./apachectl -S
VirtualHost configuration:
Syntax OK
bash-3.00#
I have added same proxy configuration outside virtual host and it is not working there as well.
kindly guide and let me know if i am missiong anything in the configuration.
<Proxy balancer://tomcatservers>
BalancerMember ajp://server_name:8009 route=tomcat4 retry=60
BalancerMember ajp://server_name:8010 route=tomcat5 retry=60
</Proxy>
<Location /*>
Allow From All
ProxyPass balancer://tomcatservers/* stickysession=JSESSIONID nofailover=off
</Location>

Your request probably isn't hitting the virtual host that you setup
the proxy directives in. Maybe the ifDefine is confusing things, or
maybe your apachectl -S says you have dead vhosts, maybe your not
testing with SSL on the frontend...

Hello Eric,
Thanks for the response.
I have now mentioned the different route.
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat5">
> <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat4">
My problem is i am trying to acheive load balancing with mod_proxy module.
When i am trying to access http URL,it's not gettign redirected to tomcat servers and just giving apache home page.
and
When i am trying to access https URL,i am getting error page is not loading.
kindly help me to find out why apache is not redirecting request to tomcat.
I have only noticed following error in the logs.
[Mon Sep 13 10:43:59 2010] [error] [client 172.17.136.151] File does not exist: /opt/web/apache2/htdocs/eMatrix

shouldn't the routes differ? You never actually mentioned how your
server "doesn't work".
