Rails - Dec 2011 - where define the script_name?

module ActionController
  module UrlFor
    extend ActiveSupport::Concern

    include AbstractController::UrlFor
I have read the rails source.In the actionpack/lib/action_controller/
metal/url_for.rb

    def url_options
      @_url_options ||= super.reverse_merge(
        :host => request.host,
        :port => request.optional_port,
        :protocol => request.protocol,
        :_path_segments => request.symbolized_path_parameters
      ).freeze

      if _routes.equal?(env["action_dispatch.routes"])
        @_url_options.dup.tap do |options|
          options[:script_name] = request.script_name.dup
          options.freeze
        end
      else
        @_url_options
      end
    end

  end
end


I don''t know where define the script_name.I execute the below command

apple@apple:~/rails$ grep --exclude-dir test -r script_name *
actionpack/lib/action_controller/metal/url_for.rb:
options[:script_name] = request.script_name.dup
actionpack/lib/action_dispatch/routing/
route_set.rb:                          :trailing_slash, :anchor, :params,
:only_path, :script_name]
actionpack/lib/action_dispatch/routing/route_set.rb:
script_name    = options.delete(:script_name)
actionpack/lib/action_dispatch/routing/route_set.rb:        path
(script_name.blank? ? _generate_prefix(options) :
script_name.chomp(''/'')).to_s
railties/lib/rails/commands/plugin.rb:
attr_reader :environment, :script_name
railties/lib/rails/commands/plugin.rb:        @script_name File.basename($0)
railties/lib/rails/commands/plugin.rb:          o.separator "
#{@script_name} plugin install http://example.com/my_svn_plugin\n"
railties/lib/rails/commands/plugin.rb:          o.separator "
#{@script_name} plugin install
git://github.com/SomeGuy/my_awesome_plugin.git\n"
railties/lib/rails/commands/plugin.rb:          o.separator "
#{@script_name} plugin install -x my_svn_plugin\n"
railties/lib/rails/commands/plugin.rb:          o.banner =    "Usage:
#{@base_command.script_name} install PLUGIN [PLUGIN [PLUGIN] ...]"
railties/lib/rails/commands/plugin.rb:          o.banner =    "Usage:
#{@base_command.script_name} remove name [name]..."
railties/lib/rails/commands/plugin.rb:          o.banner =    "Usage:
#{@base_command.script_name} info name [name]..."
railties/lib/rails/commands/runner.rb:  script_name File.basename($0)

It''s part of the environment you get from rack / your web server
(apache, nginx etc.). I''d check either the rack source or the
documentation for your web server for its precise interpretation.

The script_name is assigned in journey-19defa6acfe8/lib/journe/
router.rb

      unless route.path.anchored
          env[''SCRIPT_NAME''] = script_name.to_s + match.to_s
          env[''PATH_INFO'']   = match.post_match
        end

Mongel has script_name but it isn''t for my wanting.
