[UPHPU] Default robots.txt file

[Richard K Miller]

Our web server has a couple dozen virtualhosts. A few have their own  
robots.txt files, but for all the others I'd like to implement a  
default robots.txt. Is there a way to do this in Apache instead of  
copying or linking a file in every directory?

I tried putting this near the top of my httpd.conf but it didn't work:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule /robots.txt /www/public/robots.txt [L]

Another way to think about it would be "if you get a 404 error and  
the requested file was robots.txt, serve up the default robots.txt  
file" but I'm not sure how to translate that into Apache-speak.
