Problem moving from lighty-fastcgi to apache-mongrel

Easiest way is to just set it in a mongrel.conf. Just create a file

  ENV['site'] = ""

Name it mongrel.conf, and then start your mongrel with:

  mongrel_rails start -e production -S mongrel.conf

The mongrel.conf file is loaded before rails or anything else and it is
a ruby script.

Try it out and let me know how it works.
