Hello, It's unclear if the way to detect whether a particular response was the result of a cache hit or miss in VCL, has changed from Varnish 3 to Varnish 4.
At this page (not an official Varnish page...), it suggests using the value of resp.http.X-Varnish (whether it has a single or multiple values) to determine this: http://foshttpcache.readthedocs.org/en/latest/varnish-configuration.html# Alternatively I've also seen suggestions for continuing to use obj.hits in vcl_deliver. e.g. : sub vcl_deliver { if (obj.hits > 0) { # Add debug header to see if it's a HIT/MISS and the number of hits, disable when not needed set resp.http.X-Cache = "HIT"; } else { set resp.http.X-Cache = "MISS"; } } We've observed that the value of %{Varnish:handling}x in the varnish ncsa log has been accurate in reporting HITs vs MISSes. Could we use a VCL equivalent of this in vcl_deliver to determine whether a particular response is the result of a HIT or a MISS? Any advice on the recommended way in VCL to determine whether a response is the result of a HIT or MISS would be greatly appreciated! Thanks, Umesh
