That is a request for

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

:: www.hs.fi has address

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.

are using a very outdated Squid version. Please upgrade. Squid has been
HTTP/1.1 compliant for many years now.
