It depends if it is running as a proxy or as a accelerator.
When running as a proxy it does not care about the Host:
header as the request URI contains all information needed.
When running as a accelerator or transparent proxy then it
cares aboutthe Host: header as it is needed to determine
which virtual server the user is accessing.

Squid currently uses the HTTP/1.0+ persistent connections model:

Connection: Keep-Alive
or
Proxy-Connection: Keep-Alive

depending on if it is talking to a server or a peer.

Squid does not yet fully support HTTP/1.1 and therefore it
can't claim it is supporting HTTP/1.1 but the transition is
in progress with more and more of HTTP/1.1 supported in each
release. But until then Squid downgrades requests to HTTP/1.0
while trying to take advantage of the parts of HTTP/1.1 that
it understands and can support.
