-module ActionController
-  # In <b>routes.rb</b> one defines URL-to-controller mappings, but the reverse
-  # is also possible: an URL can be generated from one of your routing definitions.
-  # URL generation functionality is centralized in this module.
-  #
-  # See ActionDispatch::Routing and ActionController::Resources for general
-  # information about routing and routes.rb.
-  #
-  # <b>Tip:</b> If you need to generate URLs from your models or some other place,
-  # then ActionController::UrlFor is what you're looking for. Read on for
-  # an introduction.
-  #
-  # == URL generation from parameters
-  #
-  # As you may know, some functions - such as ActionController::Base#url_for
-  # and ActionView::Helpers::UrlHelper#link_to, can generate URLs given a set
-  # of parameters. For example, you've probably had the chance to write code
-  # like this in one of your views:
-  #
-  #   <%= link_to('Click here', :controller => 'users',
-  #           :action => 'new', :message => 'Welcome!') %>
-  #
-  #   #=> Generates a link to: /users/new?message=Welcome%21
-  #
-  # link_to, and all other functions that require URL generation functionality,
-  # actually use ActionController::UrlFor under the hood. And in particular,
-  # they use the ActionController::UrlFor#url_for method. One can generate
-  # the same path as the above example by using the following code:
-  #
-  #   include UrlFor
-  #   url_for(:controller => 'users',
-  #           :action => 'new',
-  #           :message => 'Welcome!',
-  #           :only_path => true)
-  #   # => "/users/new?message=Welcome%21"
-  #
-  # Notice the <tt>:only_path => true</tt> part. This is because UrlFor has no
-  # information about the website hostname that your Rails app is serving. So if you
-  # want to include the hostname as well, then you must also pass the <tt>:host</tt>
-  # argument:
-  #
-  #   include UrlFor
-  #   url_for(:controller => 'users',
-  #           :action => 'new',
-  #           :message => 'Welcome!',
-  #           :host => 'www.example.com')        # Changed this.
-  #   # => "http://www.example.com/users/new?message=Welcome%21"
-  #
-  # By default, all controllers and views have access to a special version of url_for,
-  # that already knows what the current hostname is. So if you use url_for in your
-  # controllers or your views, then you don't need to explicitly pass the <tt>:host</tt>
-  # argument.
-  #
-  # For convenience reasons, mailers provide a shortcut for ActionController::UrlFor#url_for.
-  # So within mailers, you only have to type 'url_for' instead of 'ActionController::UrlFor#url_for'
-  # in full. However, mailers don't have hostname information, and what's why you'll still
-  # have to specify the <tt>:host</tt> argument when generating URLs in mailers.
-  #
-  #
-  # == URL generation for named routes
-  #
-  # UrlFor also allows one to access methods that have been auto-generated from
-  # named routes. For example, suppose that you have a 'users' resource in your
-  # <b>routes.rb</b>:
-  #
-  #   map.resources :users
-  #
-  # This generates, among other things, the method <tt>users_path</tt>. By default,
-  # this method is accessible from your controllers, views and mailers. If you need
-  # to access this auto-generated method from other places (such as a model), then
-  # you can do that by including ActionController::UrlFor in your class:
-  #
-  #   class User < ActiveRecord::Base
-  #     include ActionController::UrlFor
-  #
-  #     def base_uri
-  #       user_path(self)
-  #     end
-  #   end
-  #
-  #   User.find(1).base_uri # => "/users/1"
-  #
-  module UrlFor
-    extend ActiveSupport::Concern
-
-    included do
-      ActionDispatch::Routing::Routes.install_helpers(self)
-
-      # Including in a class uses an inheritable hash. Modules get a plain hash.
-      if respond_to?(:class_attribute)
-        class_attribute :default_url_options
-      else
-        mattr_accessor :default_url_options
-      end
-
-      self.default_url_options = {}
-    end
-
-    # Overwrite to implement a number of default options that all url_for-based methods will use. The default options should come in
-    # the form of a hash, just like the one you would use for url_for directly. Example:
-    #
-    #   def default_url_options(options)
-    #     { :project => @project.active? ? @project.url_name : "unknown" }
-    #   end
-    #
-    # As you can infer from the example, this is mostly useful for situations where you want to centralize dynamic decisions about the
-    # urls as they stem from the business domain. Please note that any individual url_for call can always override the defaults set
-    # by this method.
-    def default_url_options(options = nil)

-        options
-      end
-    end
-
-    # Generate a url based on the options provided, default_url_options and the
-    # routes defined in routes.rb.  The following options are supported:
-    #
-    # * <tt>:only_path</tt> - If true, the relative url is returned. Defaults to +false+.
-    # * <tt>:protocol</tt> - The protocol to connect to. Defaults to 'http'.
-    # * <tt>:host</tt> - Specifies the host the link should be targeted at.
-    #   If <tt>:only_path</tt> is false, this option must be
-    #   provided either explicitly, or via +default_url_options+.
-    # * <tt>:port</tt> - Optionally specify the port to connect to.
-    # * <tt>:anchor</tt> - An anchor name to be appended to the path.
-    # * <tt>:skip_relative_url_root</tt> - If true, the url is not constructed using the
-    #   +relative_url_root+ set in ActionController::Base.relative_url_root.
-    # * <tt>:trailing_slash</tt> - If true, adds a trailing slash, as in "/archive/2009/"
-    #
-    # Any other key (<tt>:controller</tt>, <tt>:action</tt>, etc.) given to
-    # +url_for+ is forwarded to the Routes module.
-    #

-    #
-    #    url_for :controller => 'tasks', :action => 'testing', :host=>'somehost.org', :port=>'8080'    # => 'http://somehost.org:8080/tasks/testing'
