Reverse proxy for subsonic

[akaii]

Hello

I have some understanding problem for using Apache as a reverse proxy when one of virtualhost is running on tomcat like the one I'm using "subsonic".

The path of the folder is /var/subsonic/ so how can I configure Apache in order that
http://cloud.ak.net target my cloud that is running on apache2
and
http://music.ak.net target my subsonic that is running on tomcat

Thanks for your help.
