I am currently running Squid 2.2 STABLE4 on a Redhat 6.1 box. The server is
also running APACHE www services. I have succesfully configured squid to
use transparent proxy for our internal LAN's but we cannot access our www
pages (and for that matter no-one external as well), we receive the
following message;

ERROR
The requested URL could not be retrieved
----------------------------------------------------------------------------

While trying to retrieve the URL: http://www.ingram.com.au/
The following error was encountered:
Access Denied.
Access control configuration prevents your request from being allowed at

I'm guessing that I need to configure squid NOT to cache local the www.  Can
anyone help?
Regards.
