Subject: Enter version p8. first attempt at a working black and whitelisting
 scheme. The previous version had a http_access allow on both GET and POST
 request. Which ends up being the world. Has this ever worked? Removed the mac
 acl backend since it is not supported. Next step squidguard or danguardian
