How can I redirect requests to specific files above the site root?

robots.txt+favicon.ico go into => /fileserver/files/mywebsite_com/stuff

RewriteRule ^(robots.txt|favicon.ico)$ ../stuff/$1 [L]

Alias /robots.txt /fileserver/files/mywebsite_com/stuff/robots.txt

<Directory /fileserver/files/mywebsite_com/stuff>
    Order allow,deny
    Allow from all
</Directory>

ln -s /fileserver/files/mywebsite_com/stuff/robots.txt /fileserver/files/mywebsite_com/stuff/favicon.ico /fileserver/mywebsite_com/www/
