Only get, head, post, put, and delete requests are allowed. Route was not recognized. Try to find out why (maybe wrong verb). do not pass all relevant information to route.recognize as it does to recognize_optimized

class RouteSet
  def recognize_path(path, environment={})
    result = recognize_optimized(path, environment) and return result

    # Route was not recognized. Try to find out why (maybe wrong verb).
    allows = HTTP_METHODS.select { |verb| routes.find { |r| r.recognize(path, environment.merge(:method => verb)) } }

    if environment[:method] && !HTTP_METHODS.include?(environment[:method])
      raise NotImplemented.new(*allows)
    elsif !allows.empty?
      raise MethodNotAllowed.new(*allows)
    else
      raise RoutingError, "No route matches #{path.inspect} with #{environment.inspect}"
    end
  end

line

     allows = HTTP_METHODS.select { |verb| routes.find { |r| r.recognize(path, :method => verb) } }

should read

     allows = HTTP_METHODS.select { |verb| routes.find { |r| r.recognize(path, environment.merge(:method => verb)) } }

this way environment passed to routes rules

otherwise hostname_routing stop working as there is no information passed to check hostname http://weblog.jamisbuck.org/2006...
