how to create multiple applications?

I'm just starting with Ruby/Rails, and working through OnLamp's
"Rolling with etc". I got the cookbook app working OK, but now I want
to create a little project of my own.

I now realise that the url used to access a controller (say
"HelloWorld" doesn't include the "cookbook" level. So is there only one
set of controllers for a given Rails server or what? (I'm using
Webrick on XP)


There is only one set of controllers per application. When running the
default webrick-backed webserver, you can only run one Rails application,
but that is a limitation of the dinky-toy webserver, not Rails itself.
