Dear all, In the past I’ve been successfully using radiant with mod-fcgid, but now I decided to try radiant with mongrel\_cluster behing apache2 proxy\_balancer. I setup a mongrel cluster following the instruction I found [http://blog.codahale.com/2006/06/19/time-for-a-grown-up-server-rails-mongrel-apache-capistrano-and-you/](http://blog.codahale.com/2006/06/19/time-for-a-grown-up-server-rails-mongrel-apache-capistrano-and-you/) [http://blog.innerewut.de/articles/2006/04/21/scaling-rails-with-apache-2-2-mod\_proxy\_balancer-and-mongrel](http://blog.innerewut.de/articles/2006/04/21/scaling-rails-with-apache-2-2-mod_proxy_balancer-and-mongrel) My goal is to be able to deploy radiant web sites using apache VirtualHost directive, and to access the corresponding /admin panel of each web sites. I’m able to setup different virtualhost as radiant “istances”, I see the classical "Your Blog Name a really amusing tag-line here" page, but when I try to access the /admin panel I receive an error message.

[seancribbs.com](http://seancribbs.com) is deployed with this pattern (apache 2.2, mongrel), and some custom deployment tasks based on deprec 1.4.1. What is your hosting solution? Sean
