The wiki http://wiki.squid-cache.org/Features/LargeRockStore shows largerock have one goal "Reasonable range request support (e.g., avoid loading the entire file to serve a "last 100 bytes" range)." Maybe we can create a internal table to track the "ranges" and put them together to a entire file or a "not entire file" and dedup the redundant part. Then we can hit the matched part when the request with ranges head, and without configure "range_offset -1". Regards Simon
