[squid-users] Error 503, only when passing through squid

Hi all,

I am a newbie to squid. And I have struggled with its configuration file for several days, until I
got all the desired acl's correctly set.
Then I tried my configuration using wget and... 503.
I fell back to a minimal totally open configuration:
----------------------
http_port 3128
emulate_httpd_log on
debug_options ALL,5
negative_ttl 0

acl all src 0.0.0.0/0.0.0.0
acl allsites dst 0.0.0.0/0.0.0.0
acl localhost src 127.0.0.1/255.255.255.255
acl to_localhost dst 127.0.0.0/8
acl SSL_ports port 443 563
acl Safe_ports port 80 20 21 443 563 70 210 1025-65535
acl CONNECT method CONNECT
acl mysite src localhost 192.168.0.0/30 172.16.112.0/24

http_access allow CONNECT
http_access allow Safe_ports
http_access allow all
http_access allow allsites
http_reply_access allow all

coredump_dir /var/spool/squid
----------------------

But still, I get:
----------------------

######## everything is OK so far

----------------------

Obviously, it is bound to squid. I run CentOS on x86_64 architecture. I do not join the log files
here, because I found them not very helpful, only logging that there was an 503, without giving more
information about it.
I really do not know what to try now, and any clue would be very welcome and helpful.

Thanks in advance,

Philippe
