when squid request original server and original server dont response,
then squid will return http code status 0.
but tcp_hit:none means squid didnot request original http server.
very strange.
and I have ever found another strang question:
$squidclient -p 80 mgr:5min
sample_start_time = 1228439560.788657 (Fri, 05 Dec 2008 01:12:40 GMT)
sample_end_time = 1228444076.391143 (Fri, 05 Dec 2008 02:27:56 GMT)
$squidclient -p 80 mgr:info
