incoming sms

class SmsController < ApplicationController
  # GET /sms/in
  # GET /sms/in.xml
  def in
    @sms_in = params[:text]

    respond_to do |format|
      format.html # index.html.erb
      format.xml  { render :xml => @prova }
    end
  end
end

... and my routing is like:   
map.resources :sms, :collection => { :in => :get }
