A simple rails plugin that adds an action for your reverse proxy/load balancer to ping and not leave a rails log entry.
In your rails 3 app:
rails plugin install git://github.com/schlick/proxy_ping.git
You will need to add a route like so to your config/routes.rb:
map.route '/proxy_ping', :controller => 'proxy_ping', :action => 'ping'
and in your config/application.rb
require "#{Rails.root}/vendor/plugins/proxy_ping/lib/proxy_ping_logger"
