Rails 2.3 + Mongrel: Deploy with --prefix causes AbstractRequest Error

Hey guys,

I think this is more of a mongrel problem, but seeing as how that hasn't had an update in a year, I'm wondering if we can fix this on the rails side.

Using mongrel_rails start --prefix /something

now breaks, because on line 151 of mongrel/rails.rb reads

ActionController::AbstractRequest.relative_url_root = ops[:prefix] if ops[:prefix]

Since AbstractRequest has been removed, this throws a "undefined constant ActionController::AbstractRequest" error. And relative_url_root is now on ActionController::Base

I've worked around it by adding:

module ActionController
  class AbstractRequest < ActionController::Request
    def self.relative_url_root=(path)
      ActionController::Base.relative_url_root=(path)
    end
    def self.relative_url_root
      ActionController::Base.relative_url_root
    end
  end
end

to my /lib directory in my 2.3.2.1 apps

Not sure if you guys want to allow the backward compatibility or not, but wanted to bring the problem to your attention.

Thanks
