Rails 2.3.2 issue with loading global constants file

Hello,

I'm trying to upgrade to Rails 2.3.2. I have been using global constants file: config/global_constants.conf.rb

which I would use this way in controller: require 'global_constants.conf'

In Rails 2.3.2 I'm getting the following error:

no such file to load -- global_constants.conf

Do I have to put the file somewhere else?

Thanks,

Tam
