Problem statement: why ATS (4.2.1.1) recording 2 log entries (with different response header and body sizes, content types) when it sent 403 response (also observed same behavior with 502 response, but not with 404 though) .Packet capture at ATS cache showed the end user only sent one request and got only one error response
