The problem is that all your templates are hard coding a path to a resource on the server.  You're telling the browser what resource to request and you're giving it an "absolute" path.  You could also give them "relative" paths such as:

This configuration parameter is exactly what started this thread (The app-wide "prefix" setting - in the subject line) :)
And I keep learning that it's a bad idea, but haven't yet understood how to do it without such parameter.
