|

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