[plt-scheme] servlet development, again

Here is a sample servlet module that comes with the web-server:

(module a-module mzscheme
  (provide interface-version timeout start)
  (define interface-version 'v1)
  (define timeout +inf.0)
  ; start : request -> response
  (define (start initial-request)
    `(html (head (title "A Test Page"))
           (body ([bgcolor "white"])
                 (p "A simple module servlet works.")))))

You need to provide three things: timeout (a number), interface-version
(the symbol 'v1), and start (a function: request -> response)
