module ActionController

# Includes +url_for+ into the host class. The class has to provide a +RouteSet+ by implementing

# the <tt>_routes</tt> method. Otherwise, an exception will be raised.

|
# In addition to <tt>AbstractController::UrlFor</tt>, this module accesses the HTTP layer to define
|

# url options like the +host+. In order to do so, this module requires the host class
|
|
# to implement +env+ and +request+, which need to be a Rack-compatible.
