Trivial change - Change /foo to /var/www/html/private. This serves two

purposes. I dislike the use of 'foo' in documentation. But also, it
aleviates some of the confusion that people have between /foo as a URI
and /foo as a directory path. Using /var/www/html/private makes this
much less ambiguous.
