I am using 2.7.STABLE8 on Windows. No patch, just the installer from http://sourceforge.net/projects/squidwindowsmsi/ Also NOT using Store ID/Url features, also probably not using SMP either as I am not familiar with it. Not sure about the "Vary" question anyway the request/response don't contain this header. Thanks.
