inspect the response header to find cached request

[Stewart Robinson]

Hi,

You could change your vcl_deliver function in your vcl to have
something like this.

sub vcl_deliver {
	if (obj.hits > 0) {
		set resp.http.X-Cache-Action = "HIT";
		set resp.http.X-Cache-Hits = obj.hits;
	} else {
		set resp.http.X-Cache-Action = "MISS";
	}
}


This works on the 2.0x series. Can't remember off the top of my head
whether vcl_deliver has renamed obj to something else.
