That's your squid.conf customization, I presume.

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?<br>

Many things can go wrong -- the real requests may require collapsed
forwarding that you do not test, the real requests may have no-cache,
the real response may not be cachable, or there is some Range handling
bug that your test scripts do not tickle (e.g., they request ranges that
are always close to each other and are always available at the same time).</pre>

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 <b>two </b>connections to the server instead of only <b>one</b>.<br>
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?<br>

Beyond that, you would have to do detailed traffic analysis (packet
captures; ALL,2; ALL,9).

I use tcpdump rather frequently.<br>
