httpd.conf problem

[Tyler Bird <suppressed>]

Hi I am trying to deny .httaccess to overide directives in a top level 
directory  /


<VirtualHost *:80>

..

<Directory />
   AllowOverride None
</Directory>



but I am also trying to allow .htaccess in sub directories

<Directory /b>
   AllowOverride All
</Directory>

</VirtualHost>


This isn't working for me.  It seems the / Directory is applying the 
AllowOverride to the whole tree.


If I fall back to .htaccess files and just the <Directory /> section 
everything works fine.

Any ideas on my first problem?  I have looked at the apache 2.2 docs 
which we have and you can do it to it doesn't seem to work.
