RoR allows you to, as long as the env is development, change parts of the your application code and then just refresh the browser--and everything is changed, without having to restart Mongrel.

How does this work, and where in the Rails codebase is this done?

(Or, alternatively, is there some easy way to do this with Rack+Mongrel?)

Thanks so much.
