That is a request for http://194.137.237.63/uutiset/.

It is *NOT* a request for http://www.hs.fi/uutiset/.

:: www.hs.fi has address 158.127.30.40

The sender is *lying*, and Squid knows it. Please read the response I
gave in that thread you quoted.

This is one of the fundamental fixes that Squid performs to keep the
Internet actually working reliably in the presence people placing
garbage into the Host header (stuff like that "www.hs.fi" lie). It is
mandatory. Sorry.


>From the fact that the output header says "HTTP/1.0" I deduce that you
are using a very outdated Squid version. Please upgrade. Squid has been
HTTP/1.1 compliant for many years now.
