issues with mongrel and apache please help me

hey all,
I have an app working great with apache2 and mongrel_cluster.
However, I'm trying to run another application and now when I go to it falls to my second app and the vice versa. That's probably
because I messed up somewhere with the cluster.
this is the content of my conf.d/app1.proxy_cluster.conf:

<Proxy balancer://mongrel_cluster>

and this is my conf.d/app2.proxy_cluster.conf:
<Proxy balancer://mongrel_cluster>

## Maybe I need to change the name of my mongrel_cluster but I'm not
sure how to do this :confused:
## this is my sites-enabled/app1.conf:

  DocumentRoot /home/patcito/testapp/public/
Include /etc/apache2/conf.d/testapp.common

##this is my conf.d/app1.common:
<Directory "/home/patcito/testapp/public/">
    Options FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all

  RewriteEngine On

  # Make sure people go to, not
  RewriteCond %{HTTP_HOST} ^$ [NC]
  RewriteRule ^(.*)$$1 [R=301,L]

ProxyPass /images !

ProxyPass /javascripts !

#continue with other static files that should be served by apache

Alias /images /home/patcito/testapp/public/images
Alias /stylesheets /home/patcito/testapp/public/stylesheets
Alias /javascripts /home/patcito/testapp/public/javascripts

those two files for app2 are similar. Any idea what's wrong?
thanx in advance
