how to do auto redirection of a tomcat application

[Tapas Mishra]

I have a site http://social.openitup.in
right now what you are seeing is a default Tomcat6 page.
I am using mod_ajp as a front end and Apache vhost configuration for same is

<VirtualHost *:80 >

        ServerName social.openitup.in
        ServerAdmin webmaster at localhost

        ProxyRequests off
        <Proxy *>
        Order deny,allow
        Allow from all
        </Proxy>
        ProxyPreserveHost On

        ProxyPass / ajp://192.168.1.19:8009/
        ProxyPassReverse / ajp://192.168.1.19:8009/


</VirtualHost>




How ever I have an application running on it
http://social.openitup.in/olat
what I want to do is when some one opens
http://social.openitup.in
then rather than seeing Tomcat6 home page from
/var/lib/tomcat6/webapps/ROOT/index.html
the person is  redirected to olat application which is in
/var/lib/tomcat6/webapps/olat
how can this be achived?

The machine where OLAT is and where the above Reverse Proxy
configuration is are physically different machines.
