My web searching is not finding out the answers to this, so I turn to 
you all here.
I am trying to NOT modify my httpd/conf/httpd.conf file, and only make 
changes via includes.  I have done that with a 00-init.conf where I set 
things like servername and serveradmin.  Now I want to move my allow and 
denies to a 01-allow.conf include.  I tried:
<Directory "/var/www/html">
     Order allow,deny
     deny from all
</Directory>
as that seems to be what is in the default conf, but I see in the error_log:
[Tue Oct 07 08:51:58 2014] [error] [client 208.83.67.156] Directory 
index forbidden by Options directive: /var/www/html/
And maybe this is not the right restriction, because when I make this 
change directly in the default httpd.conf, I still can get to the 
default web page.
Now on to the 'allow' statement.  All syntax examples I have seen for it 
follow:
allow from 1.1.1.0/24 1.1.2.0/24 2400:cb00:2048:1::/64
and soforth.  That is each range separated by a space.  But potentially 
I have 18 ranges to specify, and at least named makes it easy with each 
range on its own line ending with a ';'.  For now I am only putting 2 
ranges in, but how does one set up a longer list of allowed ranges?
thanks
