Thanks Amos for update. I tried the same as explain by you in earlier
reply.
but after this, Proxy response degraded like anything. also HTTPS site are
not opening. So reverted back to the solution given by Eliezer.
Next, I want to restrict the URL access based on AD OU membership for
users, can you quickly help me with some starting points.
regards;
Nilesh Gavali

Not quite. CONNECT is a type of message that makes no sense sending
through another proxy if its able to go direct.
So while the never_direct rule above will make it go through the peer.
It will also make everything go through the peer, always. If the peer
goes down traffic stops going anywhere.
If you want that, then fine above is fine.
An alternative which leaves DIRECT, but only as a backup when the peer
is down is to configure:
nonhierarchical_direct off
prefer_direct on

Hey,
The issue is that CONNECT request can be passed only directly to the
origin server on 3.1.
Try to add:
never_direct allow all
To your squid.conf and see if it works.
I do not remember if it works for all versions.

Hello Antony;
I have setup like below :-
end user >> LinuxProxy(3.1.10) >> External Proxy(3.4)>> Internet
when we configure external proxy ip in end user's IE, all HTTP & HTTPS
site work properly.
when we configure Linux proxy ip in end user's IE, HTTP works fine but
none of the HTTPS site open.
when we access https site from LinuxProxy, below logs are appearing in
access.log
TCP_DENIED/407 CONNECT sitename:443 - NONE/ text/html
TCP_MISS/503 0 CONNECT sitename:443 usern...@mydomain.com DIRECT /
- -
TCP_MISS/200 23456 GET http://www.anysite.com
usern...@mydomain.com DEFAULT_PARENT/10.10.x.x text/html
what I making out from log is ( I might be wrong) - HTTPS request are
going directly instead .
attached is my Linux Proxy config-
