I'll just leave you with a dump of Mongrel starting up ... with a couple choice lines bolded ...
jimmysch-gemini-mac:SilverlightOnRails jimmy$ ./script/server => Booting Mongrel (use 'script/server webrick' to force WEBrick) => Rails application starting on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server ** Starting Mongrel listening at 0.0.0.0:3000 ** Starting Rails with development environment... ** Initializing Silverlight ** Generating client.xap ** Rails loaded. ** Loading any Rails specific GemPlugins ** Signals ready. TERM => stop. USR2 => restart. INT => stop (no restart). ** Rails signals registered. HUP => reload (without restart). It might not work well. ** Mongrel 1.1.2 available at 0.0.0.0:3000 ** Use CTRL-C to stop.
More on this later =)
