How i normally do this is to have an application.rb method which saves 
the current url to the session, and another that redirects to the stored 
url (which should have a default in case it can''t find it). Then, in 
pages which i want to bookmark for returning to (you might not want 
someone to get sent back to some pages), then save the url.

EG in application.rb

  def store_location
    session[''saved_location''] = request.request_uri
  end

  def redirect_to_back_or_default(default)
    if session[''saved_location''].nil?
      redirect_to default
    else
      redirect_to session[''return-to'']
      session[''saved_location''] = nil
    end
  end

Then, in a page that you want the user to be able to go back to:

<% store_location %>

Then, just call
''redirect_to_back_or_default(''enter your chosen default url
here,
depending on context'')

to send someone back.

I think i copied this off someone else a while ago so props if this is 
your code :)
