So it turns out that I was wrong in this. When range_offset_limit is -1KB,
Squid just grabs the requested range for suffixes (as I described above).
The same is true when range_offset_limit > 0. However, when
range_offset_limit is -1 bytes (which I was mixing with -1KB before), it
always grabs and caches the whole file, even when a suffix is requested.

So - Squid always grabs just the suffix, except when range_offset_limit is
-1 bytes. I do have a question about this though -- since -1KB isn't
really meaningful, should any negative value for range_offset_limit be
cast to -1 to prevent screw-ups like mine?

Thanks,
