My squid cache is working fine .I'm using squid 2.5-stable and os is
RHL-9.
acl myacl src 192.168.0.0/255.255.0.0
acl no100 src 192.168.0.100
#acl img url_regex [-i] ^http://img.123greetings.com.*
acl imageserv urlpath_regex [-i] img
acl someurl dstdomain .casalemedia.com
no_cache deny imageserv no100 someurl
http_access allow myacl

# And finally deny all other access to this proxy
http_access allow localhost
http_access deny all

my cache dir and other things are also ok.
But the problem is that it caching the 404 Error Msg.I want to no cache
for all Error Msg.Error Msg should not be cached.How can I do that.Is
that possible.Plz help.
It's urgent.
