I meant the latter... yes, the missing file is $appdir/public/css/style.css

And, the above is exactly what I am not getting.

What is the auto_page feature, and how do I use it? In any case, I
have my pages in a database, so my logic is, if a page is explicitly
requested as a param in path_info, retrieve that from the db and serve
it up. If no page is defined, then serve a default page.

I have also now discovered that ProxyPass doesn't handle trailing slashes.

    ProxyPass /punkishdance/ http://localhost:3000/
    ProxyPassReverse /punkishdance/ http://localhost:3000/

lets me get to http://localhost/punkishdance/ but not to
http://localhost/punkishdance

I can define two separate rules,

    ProxyPass /punkishdance http://localhost:3000/
    ProxyPassReverse /punkishdance http://localhost:3000/

and that seems to work, but Apache warns me with the following error

[Mon Mar 08 17:34:50 2010] [warn] worker http://localhost:3000/
already used by another worker


Seems like the only way around this is to also involve mod_rewrite with

    RewriteRule ^/punkishdance$ punkishdance/ [R]

and, I was hoping to avoid mod_rewrite completely.
