You should print out HTTP headers.  You can use them to report some status.

Something like:

#!/usr/local/bin/clisp -q -ansi -norc -E utf-8
;; -*- mode:lisp;coding:utf-8 -*-

(defun main ()
  (write-string "Content-Type: text/plain
Content-Length: 0
Status: 204


")
  (finish-output)
  (ext:exit 0))

(main)
