The squid I have running locally certainly does (2.1.2-2 as packaged by
Debian).  It adds header lines like
        Age: 767
        X-Cache: HIT from kweide.tezcat.com
        Proxy-Connection: close
when serving from cache, even when responding to a HEAD.  And it removes
Set-Cookie lines in that case, even if there aren't any Cache-Control
directives telling it so.

Actually, it seems to serve HEAD from cache even when a GET with the
same request headers would not use the cached copy.
Of course, that may be a matter of how I have it configured.  I don't
remember whether I did anything unusual.

I wasn't really thinking about shared, non-private caches.
