This is because Squid loops back on itself when you try to proxy the
accelerated host..

Browser -> Squid Proxy -> Squid Accelerator [ -> Real server ]

Squid denies the request because it does not like to see requests from
itself.

Simplest fix is to use a redirector to rewrite proxy requests to match
the backend server name, like what httpd_accel_host/port does on
accelerated requests.
