Ruby on Rails

Rails routes are built when the app starts (or if you're under a lot of traffic, if you fork a new Apache process). Rails is a long-running process, and it does not reload at each request. You would have to restart the server to have a change in routes make a difference. If you've deployed with Passenger, then touch tmp/restart.txt will do the trick.
