how to configure ProxyPass for tomcat for app which generates url at root /
I basically have 2 applications
http://sakai.openitup.in
http://olat.openitup.in
we wanted both of these to be accessible as
http://research.openitup.in/sakai
http://research.openitup.in/olat
and a website http://reserach.openitup.in which is separate from both of these
but what I found was if I proxy root of these apps (sakai and olat)
using a URL for these apps only (i.e. sakai.openitup.in and olat.openitup.in)
then things work.
i.e.
vhost for sakai.openitup.in
<VirtualHost *:80 >

ServerName sakai.openitup.in
ProxyPass / ajp://192.168.1.14:8009/
ProxyPassReverse / ajp://192.168.1.14:8009/

</VirtualHost>

and for olat another vhost

<VirtualHost *:80 >

ServerName olat.openitup.in
ProxyPass / ajp://192.168.1.15:8009/
ProxyPassReverse / ajp://192.168.1.15:8009/

</VirtualHost>

then things work.
But if I use in the vhost research.openitup.in

<VirtualHost *:80 >
ServerName research.openitup.in

ProxyPass /sakai ajp://192.168.1.14:8009/
ProxyPassReverse /sakai ajp://192.168.1.14:8009/

ProxyPass /olat ajp://192.168.1.15:8009/
ProxyPassReverse /olat ajp://192.168.1.15:8009/


ProxyPass / http://192.168.1.14
ProxyPassReverse / http://192.168.1.14
</VirtualHost>

in the vhost of research.openitup.in then
http://research.openitup.in/sakai
http://research.openitup.in/olat
are not accessible.

If you notice I have forwarded root of research.openitup.in to an internal
machine.
Which is where it actually is so ProxyPass / for research.openitup.in is needed.

So in this situation what can be a possible solution for me so that I can access
http://research.openitup.in/sakai
and not http://sakai.openitup.in and same for olat

http://research.openitup.in/olat

and not http://olat.openitup.in

Let me know if some one has some suggestion for this part.

Firstly: Have you correctly configured mod_jk? Do you have a mod_jk
log file? What is in it? What is in your error log?

Secondlyl: If in ProxyPass the LHS ends in a / the RHS must end in a
slash too. But better not use slash at all:
ProxyPass /sakai ajp://192.168.1.14:8009

And have a look at what links your application generates. ProxyPass
and ProxyPassReverse do not change anything in the content of the html
returned by the app. You can use mod_proxyhtml to mangle the html for
you, but a better solution is to make your application aware of the
fact that it is behind a proxy.
Look at the documentation of the application and see if there is a
configuration setting to define the base URL, and set that to
http://research.openitup.in/sakai

If he's using ProxyPass for this, then mod_jk is irrelevant; this is
using mod_proxy and mod_proxy_ajp.
