Using a directory name as a parameter

I'd like to use a directory name as a parameter only if the directory does not exist at root level.

For instance,

http://www.mydomain.com/foo/
Should execute http://www.mydomain.com/index.php?param=foo

However, http://www.mydomain.com/ExistingFolder/
Should execute http://www.mydomain.com/ExistingFolder/index.php

This only needs to be done at root level... eg:
http://www.mydomain.com/ExistingFolder/foo
should *not* execute http://www.mydomain.com/ExistingFolder/index.php?param=foo
but rather http://www.mydomain.com/ExistingFolder/foo/

Thanks,

I modified http.conf to have the following:

DirectoryIndex index.html index.php index.html.var
RewriteEngine on
# check, if element is not a directory
RewriteCond c:/dev/htdocs/$1 !-d
RewriteRule ^([^/]+)/$ /index.php?param=$1 [L]

...and restarted the service. (I'm using apache2, but that shouldnt matter)

When I go to http://localhost/foo/ or http://localhost/foo/bar/ [foo doesnt exist]

I just get a 404.. no rewrite is attempted. http://localhost/index.php exists and echos $_GET['param']

Am I doing anything wrong?

Ok, I changed the regex to just:

^/(.*)/$

Seems to be working the way I wanted it to.
