Right. The model of mod_lisp is to have a process separate from
Apache-httpd for handling the desired requests. The mod_lisp module
forwards the request, and copies back the response. Your lisp process
reads the headers (and POST data), and sends a constructed response.
Note that mod_lisp is not particularly "lispy". It doesn't communicated
in s-expressions. But, it is a very simple protocol. I wrote a scheme
end of the bare-bones protocol
(http://sourceforge.net/project/showfiles.php?group_id=141512).

You can pick any port you want for the mod_lisp-to-lisp-server
communication.

Look through the various Apache directives (try the "quick reference"
section), searching for "CGI". Here's what I found:

ScriptAlias
Straight URL (path) -> CGI Script. So, by URL, rather than directory.

ScriptAliasMatch
Pattern match URL -> CGI. So, you could match by extension (or any part
of the URL-path).

Script
Activate a CGI based on the method (GET, POST, etc.).

Action
Seems to be able to map an extension or mime-type to a CGI (in
conjunction with AddHandler).

AddHandler
Specifically maps extensions to cgi handlers. Use Action to map the
"handler-name" to the cgi-script.

Read the "Handler" section, and the mod_cgi section.
