Rails - Jun 2005 - Translating URL file extensions

I want to translate any URL that ends in .vxml to an action.

For example, I want

  /requester/create_session.vxml  

to translate to

  :controller => ''requester''
  :action => ''create_session''
  :extension => ''vxml''

This is what I did to make this work:

In routes.rb I added:

  map.connect '':controller/:vxml'', :action =>
''process_vxml'',
              :requirements => {:vxml => /.*\.vxml/}

In requester_controller, I added:

  def process_vxml
    @params[:action] = @params[:vxml].sub(/\.vxml/, '''')
    @params[:extension] = ''vxml''
    send @params[:action]
  end

Is there an easier (cleaner) way of doing this? Thanks
