[squid-users] never_direct + https site access problem in sandwich setup!!!

Hi all
  I am running a squid1->DG->squid2 sandwich setup and i am facing
the following problem.
When i give "never_direct allow all" in squid1.conf , i am not able to
access any https sites.
Without the above configuration line , all users can access https
sites and even sites denied in the Content filter. For eg: suppose
http://www.redhat.com is a banned site in content filter, i am able to
access https://www.redhat.com which byepasses the content filter and
is served by squid2.

  My requirement is to allow all https traffic through this setup but
the requests should flow through content filter and then to squid2
for serving. Is it possible to tell squid1 to pass the https traffic
to the content filter and then to squid2?

The Ports used here are 3128->8080->8081 .

Following is the configuration of my
squid1.conf
