squid+iptables cant access stels.sec.samsung.com only - plz help

[needee]

Dear Experts
OS: SUSE Enterprise Server 10
#rpm -q iptables
iptables-1.3.5-13.2
#rpm -q squid
squid-2.5.STABLE12-18.2
Squid server is configured to run as a transparent proxy server. iptables, and squid are running on a single machine.

Dear all I have attached the /etc/squid/squid.conf, /var/log/squid/access.log and iptables-script file, ... every thing is working fine users can browse almost all website and can chat using msn, and yahoo mesengers.

Prblm: ;(
when any client(either using win xp+IE, or either Linux+firefox) try to access the http://stels.sec.samsung.com/, browser doesnt show any thing, i.e web browser shows the blank page, while on status bar of web-browser(IE, or Firefox), it shows the status "Done".
But when I connect any of the client machine to the internet directly, i can access http://stels.sec.samsung.com/ ... no prblm

plz help, what should I do, so that my clients can access http://stels.sec.samsung.com/ if they are behind Proxy+Firewall server

Thanks in anticipation
Regards
Needee

issue resolved
Simply uninstalled the squid rpm
#rpm -e squid
downloaded the latest stable version of squid(2.6-STABLE12),and issue resolved, that is now i can access http://stels.sec.samsung.com, behind/using the squid server

I think that its a bug in the binary version of squid(squid-2.5.STABLE12-18.2), shiped with SLES 10.
