I have been searching for the definitive answers regarding routes and  
new controllers, so far no clear statement: Rails 2+ route  
generation, is it done only once at start up of mongrel? Is this only  
a dependency on how mongrel does things - looking for updates of  
config files on the fly or is it a Rails limitation?

You see I also have used servlets and JSP, it seems there you can add  
new jars and new jsps using them - and they will be picked up with the  
correct settings. There are some changes in web.xml and I think other  
configs that require a restart, but I thought that was annoying -  
especially when doing rapid, iterative development.

However, I thought when I started on Rails 1.x that I had the ability  
to even add new controllers and not restart - maybe I am wishing I  
could do that. Is this recent?

Thanks for any links or insight.
