[racket] Web server and URL dispatch

http://docs.racket-lang.org/web-server/run.html#(part._.Examples)

contains this...

>>>

(serve/servlet my-app
               #:servlet-regexp #rx"")
<<<

Where do you think a different example should go? Somewhere on

http://docs.racket-lang.org/web-server/dispatch.html

?
