Dear all!
Recently many Webapp packages contain complicated constructions to allow/deny access to directories; those constructions can IMHO be simplified.
1) Allow access. To ensured that access on Apache 2.4 is allowed it must be ensured that the compatibility module (if installed) allows access _and_ the new module, too. Both could inherit DENY from other paths:
<IfVersion >= 2.4>
<IfModule mod_access_compat.c>
Order allow,deny
Allow from all
</IfModule>
Require all granted
</IfVersion>
