I tried with a simple string before, but then i got a quite clear error message from mzscheme m3
1.1.4, which says at the end that it expected a path for the #:servlet-path keyword (see below)!
I hope this is just a misleading error message or a buggy version, because this behavious doesn't
work on the one hand and contradicts the documentation [1] on the other hand.  1.4.3. has been
compiling on my G3 PPC/Debian for three hours now, so i hope it will finish sooner or later and i
can confirm that it works with it. :) thank you for your example, i learned from it a lot, and
now that i am reading the dispatcher docs i am pretty sure i will try it because it's a very
useful and elegant thing and seems to be exactly what i was looking for! working with Scheme is
like LSD: modify your consciousness for sure and sometimes it's a bad trip. %o

(file "/usr/local/plt/lib/plt/collects/web-server/default-web-root/././servlets/code.ss") broke
the contract 
   ((-> request? response?))
    (listof module-path?)
 on serve/servlet; expected <path?>, given: "/code.ss"
