Apache as Proxy Server

I wan't to use apache as a proxy server. I have it working at the moment.

The way I have it setup it will block ALL internet requests. What I want to add then is a couple sites that are ok i.e intranet sites. I can't find a statment to use along site "ProxyBlock *" to allow some sites. Its easier this way then to specify all domains on the internet lol.

<IfModule mod_proxy.c>
ProxyRequests On
<Proxy *>
Order deny,allow
Deny from all
Allow from (lan)
</Proxy>
</IfModule>
ProxyBlock *

Concept rocks man,

Explain in detail let me try it, since I am not an expert in this.

Add these lines in you apache config and apache works as a proxy server. Except the last line that will block all url requests.

<IfModule mod_proxy.c>
ProxyRequests On
<Proxy *>
Order deny,allow
Deny from all
Allow from (lan)
</Proxy>
</IfModule>
ProxyBlock *

It actually works. Only problem is not much control on acls for urls like squid. So it won't work for me
