Hi Nils, I tried to reproduce this bug on my laptop:. I tried several times to download txt file with which webserver is sending Vary header in this way: # my squid is running on VM with IP 192.168.122.120 $ http_proxy=http://192.168.122.120:8080/ wget -O /dev/null -S http://www.ietf.org/rfc/rfc3280.txt In access.log file I had this: 1429699953.761 1060 192.168.122.1 TCP_MISS/200 296764 GET http://www.ietf.org/rfc/rfc3280.txt - HIER_DIRECT/104.20.0.85 text/plain 1429700057.740 1607 192.168.122.1 TCP_MISS/200 296750 GET http://www.ietf.org/rfc/rfc3280.txt - HIER_DIRECT/104.20.1.85 text/plain 1429700060.228 688 192.168.122.1 TCP_MISS/200 296759 GET http://www.ietf.org/rfc/rfc3280.txt - HIER_DIRECT/104.20.1.85 text/plain After backporting patch, which you have proposed (http://bugs.squid-cache.org/show_bug.cgi?id=3806), I'm not getting TCP_MISS, so bug is fixed. access.log after applying patch: 1429705109.494 1082 192.168.122.1 TCP_MISS/200 296836 GET http://www.ietf.org/rfc/rfc3280.txt - HIER_DIRECT/104.20.0.85 text/plain 1429705110.876 16 192.168.122.1 TCP_MEM_HIT/200 296607 GET http://www.ietf.org/rfc/rfc3280.txt - HIER_NONE/- text/plain 1429705113.691 15 192.168.122.1 TCP_MEM_HIT/200 296607 GET http://www.ietf.org/rfc/rfc3280.txt - HIER_NONE/- text/plain Created attachment 1017404 [details]
