fpweb/fcl-web URL syntax for Modules and Actions?

I am attempting to set up an fpweb project using a single module and
multiple actions.  After banging my head against the wall for a while
I went back and compiled the "session" demo which ships with Lazarus
only to find that the same problems seem to exist there.  I am not
certain whether the problem lies with my environment or the package
itself, so if anybody could shed some light on this I'd really
appreciate it.

Here is the problem.  If I have a single module and a default action
then I can access the cgi server using the following URL (assuming the
session demo is in place):
http://localhost/cgi-bin/sessiondemo.cgi?module=session

I can then refresh (which changes the default action behind the
scenes) and a second action is fired, so I know at least that part is
working, but bear in mind that the URL has not changed at this point.

Per the documentation I should be able to access the module using a
"shortcut" of:
http://localhost/cgi-bin/sessiondemo.cgi/session

The above URL simply returns an error of "Could not determine HTTP
module for request 'cgi-bin'".

I am also completely unable to specify any URL that returns a specific
action.  Any time I do I either get the error message above or
something to the effect of "Could not determine HTTP module for
request 'session?action=EndSession'" or whatever syntax I attempted to
use.  This is really the issue for me -- I can live with not having
the URL shortcut -- it's all internal to my calling application
anyway.  What I really need is the ability to specify an action on the
calling side.  Without that fpweb is completely worthless and I've
wasted a bunch of time planning for it.

Here's the kicker: I am testing on IIS 6.0, and I know that everyone
seems to be working with Apache when it comes to fpweb, but I really
need IIS for the project I am working on.  I'd be more than happy to
provide details on my IIS configuration, but its almost a default
install with sufficient access granted to the IWAM account to execute
cgi and write out a log file for testing purpose in my cgi-bin
folder.  Thanks in advance for any help that you guys can offer.

OK, correction, I am now able to get actions to execute using the
session demo project by specifying the following URL:

http://localhost/cgi-
bin/sessiondemo.cgi?module=session&demosession=[actionname]

I had missed the fact that the session demo had an action variable
defined renaming the expected URL specifier "action" with
"demosession" when entering URLs.  Unfortunately I'm still unable to
use any of the shortcut syntax, and I can't seem to reproduce the
results described above with my own project despite a basically
identical configuration.  I really feel like the documentation for
this package is lacking in this area.
