A simple thing that I do when deploying a CGI app is using a soft link
instead of a rewrite rule:

    cd /var/www/cgi-bin # your system's cgi-bin may be at a different location
    ln -s /path/to/myapp/public/dispatch.cgi myapp

You need to tell your web server to treat '^/myapp' as a cgi script.
Then you can visit http://<domain>/myapp and it will be the root of
your app.  uri_for("/dog") should then return

I usually deploy as CGI for playing around or for development.  When
deploying for production, I use FastCGI, and then it is easy to mount
your app to '/' or '/whatever'.
