On Squid 3.5.7 the same result:

1442420915.874 207879 127.0.0.1 TAG_NONE/200 0 CONNECT
torproject.org:443 - HIER_DIRECT/2001:41b8:202:deb:213:21ff:fe20:1426 -

torproject.org:443 - HIER_DIRECT/38.229.72.16 -

Config snippet is:


# SSL bump rules
sslproxy_cert_error allow all
acl DiscoverSNIHost at_step SslBump1
ssl_bump peek DiscoverSNIHost
acl NoSSLIntercept ssl::server_name_regex -i localhost \.icq\.* kaspi\.kz
ssl_bump splice NoSSLIntercept
ssl_bump bump all

# Privoxy+Tor access rules
never_direct allow tor_url

# And finally deny all other access to this proxy
http_access deny all

# -------------------------------------
# HTTP parameters
# -------------------------------------

# Local Privoxy is cache parent
cache_peer 127.0.0.1 parent 8118 0 no-query no-digest default

cache_peer_access 127.0.0.1 allow tor_url
cache_peer_access 127.0.0.1 deny all
