I added the config below to squid-3.0-stable14 here, it works fine.

cache_peer 64.94.92.31 parent 80 0 no-query front-end-https=auto
originserver name=origin_3_1
acl service_3 dstdomain kb.4d.com
cache_peer_access origin_3_1 allow service_3

How are you using squid for the site? with a reverse proxy? what's the
squid version?

Passing https requests through Squid need additional config like the SSL
certificate and private key.
You may double check squid.conf and logs for details.

YES Squid won't modify HTTP response body unless you specify it to do that.
