I'm not sure I understand your explanation. You say you're using periodically_call_remote which would lead me to expect that in your controller (assuming that's where you're responding), you'd be using render :update do |page| page.replace_html (or some variation) ... end But you say your controller 'answers with a render(:partial ...) I'll take a stab below, but if that doesn't get it please post relevant code. > When the controller knows that > nothing in the display has changed, I wish to respond with the > equivalent of a '200 OK' response. How can I code that in the > controller? If you're returning html, you can just use head (in ActionController::Base) return head(:success) render I'm not sure how to return just a header with js cause I've never needed to do it, but the first thing I'd probably try would be: render :js => '' or render :js => '', :status => :success If for whatever reason those didn't work, I'd probably create an empty element on the page and... render :update do |page| page.replace_html 'empty_element', '' end HTH, Bill --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
