Very simple apache question

[Jason Green]

As I've mentioned before, I'm a linux newbie.  I'm trying to replace our
proxy server (current MS Proxy) with apache's proxy module.  It worked fine
when I downloaded the Windows version.  However, I wanted more
stability/reliability, so I installed Mandrake 8.0 on a P200.  I used the
same httpd.conf settings for the proxy section, but when I try to use it as
a http proxy, the clients get a message from my apache server saying
"Forbidden:  You dont' have permission to access http://www.whatever.com on
this server" (doesn't matter what site I go to).  All I want right now is
the ability to cache web pages for users in this office.  Here's part of my
current httpd.conf:

...
LoadModule proxy_module      modules/libproxy.so
...
AddModule mod_proxy.c
...
<IfModule mod_proxy.c>
  ProxyRequests on
  <Directory proxy:*>
    Order deny,allow
    Deny from notkpm-net.com
    Allow from kpm-net.com    (I've even tried all)
  </Directory>
  ProxyVia On
  CacheRoot /var/httpd/cache
  CacheSize 50000
  CacheGcInterval 4
  CacheMaxEmpire 24
  CacheLastModifiedFactor 0.1
  CacheDefaultExpire 1
<IfModule>

Is there something else that I'm missing somewhere?  Any help would be
appreciated.  Thanks!
