Sorry, but what is "vbr" ? >The issue is that the player is using vbr < I do not understand your question. First of all, the request usually is not simply >r8---sn-nhpax-ua8e.googlevideo.com< but also contains add. info, like itag, id, and, most important, range=xxx-yyy. I was always afraid, that youtube/google might start to make xxx-yyy more or less random, as this will definitely kill cachability,unless sombody writes some very smart code to join/extract the various parts. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Do-we-have-an-algorithm-to-define-the-cachabillity-of-an-object-by-the-request-and-response-tp4665473p4665474.html Sent from the Squid - Users mailing list archive at Nabble.com.
