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 username at MYDOMAIN.COM
<mailto:username at MYDOMAIN.COM> DIRECT / - -
TCP_MISS/200 23456 GET <http://www.anysite.com/>
http://www.anysite.com username at MYDOMAIN.COM <mailto:username at 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-
