Squid 3.2 is not even on the drawing boards yet.
Did you mean 3.0.STABLE2 ?

The problems you are seeing below is looks to be that in this case
HTTP/1.1 is further along in 3.x than your 2.6. The 3.x is adding some
headers for increased HTTP support in future.

The Squid Developers have no plans to decrease squids
standards-compliance before the protocols are expired.

The best thing for you is to fix your scripts to be able to cope with
modern web traffic. RFCs REQUIRE software to ignore headers they don't
understand.

The fast way is to build squid with HTTP-violations enabled and turn off
via in squid.conf.

PS: Be warned such action may cause other non-standard behaviour now or
in future that affects your web browsing.
