Re: bug or missconfiguration??

The problem is that you use the same Squid as accelerator and proxy.

Squid will first proxy the request, then send contact itself as the
origin server, and third it denies the request since it loops back to
itself with a warning to cache.log.

Recommended action:
Use the no-proxy settings in your browser to not use the Squid proxy to
reach your accelerated site.

Other possible actions:
a) Use a redirector, emulating what httpd_accel_host/port does on
proxied requests for your server.

b) Split your Squid into two installations. One proxy and one
accelerator.
