The squid won't send a Range: header to the server because the request 
is matching the range_offset_limit -1 ACL. I presume. So squid will try 
to fetch the file from the beginning, faking a full request, right?

Well, if I turn off collapsed_forwarding and try to GET the same file on 
the same server in a row (only changing the Range), it will create *two 
*connections to the server instead of only *one*.
I use "override-expire ignore-private ignore-no-store ignore-reload 
ignore-must-revalidate store-stale" for this particular request, won't 
it override the no-cache or whatever?

I use tcpdump rather frequently.
