Webware for Python

Hi,

I'm developing two pages, one called "faq.py" and the other called
"getlists.py". Depending on how I access them, their availability changes:
(apologies to those not using monospace fonts)

via mod_webkit:

http://blah.com/WKMod/devel/faq.py                -- WORKS
http://blah.com/WKMod/devel/faq                   -- WORKS
http://blah.com/WKMod/devel/getlists.py?x=1       -- WORKS
http://blah.com/WKMod/devel/getlists?x=1          -- WORKS

Via OneShot.cgi:

http://blah.com/OneShot.cgi/devel/faq.py          -- WORKS
http://blah.com/OneShot.cgi/devel/faq             -- WORKS
http://blah.com/OneShot.cgi/devel/getlists.py?x=1 -- WORKS
http://blah.com/OneShot.cgi/devel/getlists?x=1    -- NO WORKIE (404)!

Permissions are identical on these two files. Any ideas?

Steve
