[Catalyst] Catalyst in reverse proxy mode

[Andy Grundman]

Here is a working Apache2 -> Apache1 mod_proxy setup for a Catalyst app. 
  Note that Catalyst's built-in support for proxy environments takes 
care of server and user address rewriting on the backend automatically.

Apache2
-------
<VirtualHost *>
         ServerName www.myapp.com
         ServerAlias myapp.com
         DocumentRoot /var/www/myapp.com/root

         CustomLog /var/log/apache2/myapp.com-access_log combined

         RewriteEngine on

         RewriteRule (images|static) - [last]
         RewriteRule ^/(.*)$ http://127.0.0.1:8084/$1 [proxy]
         ProxyPassReverse / http://127.0.0.1:8084/
</VirtualHost>

Apache1
-------
Listen 127.0.0.1:8084
<VirtualHost 127.0.0.1:8084>

     ServerName www.myapp.com

     DocumentRoot /var/www/myapp.com/root
     ErrorLog /var/log/apache-perl/myapp.com-error_log

     <Perl>
             use lib qw(/var/www/myapp.com/lib);
     </Perl>

     PerlModule              MyApp
     SetHandler              perl-script
     PerlHandler             MyApp
     PerlTransHandler        Apache::OK
</VirtualHost>
