18	* mod_actions.c: executes scripts based on MIME type or HTTP method
19	*
20	* by Alexei Kosut; based on mod_cgi.c, mod_mime.c and mod_includes.c,
21	* adapted by rst from original NCSA code by Rob McCool
22	*
23	* Usage instructions:
24	*
25	* Action mime/type /cgi-bin/script
26	*
27	* will activate /cgi-bin/script when a file of content type mime/type is
28	* requested. It sends the URL and file path of the requested document using
29	* the standard CGI PATH_INFO and PATH_TRANSLATED environment variables.
30	*
31	* Script PUT /cgi-bin/script
32	*
33	* will activate /cgi-bin/script when a request is received with the
34	* HTTP method "PUT".  The available method names are defined in httpd.h.
35	* If the method is GET, the script will only be activated if the requested
36	* URI includes query information (stuff after a ?-mark).
