>Description:
"Allow from" directive in httpd.conf does not support multiple variant
notations, NOR does it support multiple CIDR notations in the same statement.

Specifically, if I have a config such as:

--snip--
Allow from 10.0.0.0/8, 199.245.173.0/24
--snip--

Apache will DIE with reason:

Syntax error on line xx of /usr/local/apache/conf/httpd.conf:
syntax error in mask portion of network/netmask    

Obviously this is an incorect error message.  There is nothing wrong with the
CIDR notation: Apache just did not interpret/parse it correctly.

Similar invalid notations:

- Mixing CIDR and hostnames.

Specifically:

--snip--
Allow from 10.0.0.0/8, some.other.hostname
--snip--

.. this will refuse some.other.hostname with an error message in error_log
stating "[client ip.add.re.ss] client denied by server configuration: $CONFIG"

The only solution was to break each notation into individual allow from's:

--snip--
Allow from 10.0.0.0/8
Allow from 199.245.173.0/24
Allow from some.other.hostname, *.hostname.com   <- this works!
--snip--

Thanks.
>How-To-Repeat:
Two courses of action:

1) (Less optimal) Note in documentation somewhere that you can't do it
2) (Best) analyze and fix parsing of config..
