There are a few settings related to how we interact with various content encodings etc., and some of that semantics was augmented fairly recently (4.2 I think). — leif > > Jay > > From: jianli Li <jia...@cisco.com> > Reply-To: "us...@trafficserver.apache.org" <us...@trafficserver.apache.org> > Date: Tuesday, September 30, 2014 at 1:11 PM > To: "us...@trafficserver.apache.org" <us...@trafficserver.apache.org> > Cc: "dev@trafficserver.apache.org" <dev@trafficserver.apache.org> > Subject: why my proxy.node.cache_hit_ratio drops > > Hi, guys > > I configured ATS as full transparent proxy, but I found the > proxy.node.cache_hit_ratio dropped when I played the same video from client > every time.
