Thanks Amos! It works.
New problem:
I am checking whether a url (object) is cached or not by using:
squidclient -p 3129 $url | fgrep X-Cache
I am getting a lot of messy code and when I quit (CRTL-C), squid logs are showing TCP_HIT_ABORTED.
How can I not get the messy code and just get the result of fgrep.
Thanks

Problem #1;
you are missing a '/' on the end of the URL. That type of URL is not
valid in HTTP/1.0. It has only recently become acceptible in HTTP/1.1,
so not all services support it.

Problem #2;
you are sending the request to an intercept port without having gone
through the NAT system.
If you left it to run, your machine would eventually crash as all
networking sockets and resources were consumed by the forwarding loop.
squidclient needs to use a forward-proxy port to connect to Squid.
Usually that is 3128, which is the port registered for Squid
forward-proxy ctraffic.
Recommended practice is to leave port 3128 for proxy administrative
access and tools like squidclient. Movine the intercept port to another
random number and firewall it (in iptables with mangle tables rule) to
prevent anything except NAT'd traffic reaching that random port.
