<Directory> and <Files> blocks are applied when apache is planning to
serve a file, which can be bypassed if it isn't strictly a file it is
serving.

For instance, proxying never ends up with apache looking at a file on
disk, so with this config:

DocumentRoot /var/empty
<Directory /var/empty>
  Order allow,deny
  Deny from all
</Directory>
ProxyPass / http://app/

requests would always be allowed - everything goes thru proxy, not the
file system.

If you change from the <Directory> approach to the <Location>
approach, does it then work correctly? IE, map out exclusions in URL
space, not filesystem space.

Cheers

Tom
