Hello Amos, Squid was not able to cache partial content 206 Responses such as this link below: http://dc122.4shared.com/img/97459254/dcf5c10e/dlink__2Fdownload_2Fe1D3g7qW_3Ftsid_3D20111124-220446-e01441a0/preview.mp3?sId=qnwkz3H9Cqm2NezD&t=1322172503748&s=fb361cc0390859a718b67a4646f7c16c AS I can see , the response doesnt have Content_range which make it harder to understand .. What are the tricky things to cache this response using Squid ? Ghassan
