What's the difference between rack app vs. rails app?

Asked 2011-06-03T18:03:47.973

I uploaded my rails 2.3.8 app to DreamHost and got an error about rack version incompatibility. I issued a support ticket and the service guy recommended that I delete config.ru.

That solved the problem. But I wonder what that would affect.

Is it ok that a rails app goes without config.ru?

you should check those two RailsCasts:

http://railscasts.com/episodes/150-rails-metal
and perhaps: http://railscasts.com/episodes/222-rack-in-rails-3
