[racket] Problem with default-indices files in Web-Server

Indexes are used by the file server to turn a directory request into a
file request if the file exists.

What you want is some default behavior if there is no other handler
for a request, you could do that with a lift [1] dispatcher where the
procedure was just (lambda (req) (redirect-to "/index.rkt")) or
something that looked at the request's URL, found it to be a
directory, and then redirected to /index.rkt.

If you have your file server setup to serve a directory that contains
the servlet source, then if requests for those files get to it, then
they'll be served as source... because they are just files to that
