Bill Clementson has <a
href="http://bc.tech.coop/blog/041111.html">written</a> about getting
TBNL up and running with apache and mod_lisp. In this example I'm
going to use <a href="http://weitz.de/hunchentoot/">hunchentoot</a>, a
pure lisp web server by (again) Edi Weitz.

;; let's test a POST request without content length and with chunked transfer encoding -
