quick_abort_min -1 KB
range_offset_limit -1 KB

The first disables quick_abort, making Squid continue "downloading" the
file even after the client has disconnected.

The second enables full range prefetching, making Squid always fetch the
complete file and then split it in ranges.

Squid does not differentiate between someone closing the window while
downloading from someone requesting just a part of the file. In both
cases it was a partial request, and if quick_abort is enabled (the
default) then Squid will stop downloading the object and discard the
result when no client is listening for the result.
