I would recommend to use spiffy instead iof the raw http extension.
The most convenient way is to use either .ssp pages or
`define-http-resource'. These should show the error messages in
the generated web-page.

There is currently no way to gracefully terminate the server. I haven't
found yet a decent method of handling all pending requests before
terminating (but I'll take a look and see what I can do).

It is, starting with version 1.89. Here is a simple example that
should run the server under csi in a separate thread without blocking
the REPL:

; this uses spiffy:

(define (spiff . args)
  (thread-start!
   (lambda ()
     (apply start-server (append args (list root: "~/stuff" port: 8080
debug: #t))) ) ) )
