Rails 3.0, setting asset_host class

I am upgrading to Rails 3.0, but am having a difficult time getting it
to boot. I have a custom asset host class that passes the name of the
asset host into its constructor. I set this class in each of the
environment configuration file. For instance, in development.rb, I
have:

ActionController::Base.asset_host = AssetHostingWithSsl.new("http://
asset%d.awesomeapp.local")

However, when trying to get rails to load, I get the following error:

"uninitialized constant AssetHostingWithSsl (NameError)"

I have asset_hosting_with_ssl.rb with the class definition in the lib
directory, which should be in the load path.

Any ideas?

As of Rails 3, the lib directory isn't autoloaded. You can either
require the file manually where you need it, or tell Rails to autoload
lib (in environment.rb), or create a new directory for autoloaded
files tell Rails to autoload that.

Ok, thanks. I think I'll put it in an initializer, actually, as
that's where it seems most of the configuration is headed to.
