Is there a way to determine if an ESI call came from cache or a backend?
I am trying to set a HTTP header on an ESI cache hit or miss, but am not having
as much success as when checking for a non-ESI request.
In the recv, I set do_esi to true and the x-esi-request value, in deliver I
have the code below which doesn't seem to work at all. I don't see any
X-ESI-Cache headers in varnishlog
In vcl_deliver:
if(obj.hits > 0){
if(resp.http.x-esi-request == "Yes"){ set resp.http.X-ESI-Cache =
"Cached"; }
set resp.http.X-Cache = "Cached";
set resp.http.X-Hits = obj.hits;
} else {
if(resp.http.x-esi-request == "Yes"){ set resp.http.X-ESI-Cache =
"Fresh"; }
set resp.http.X-Cache = "Fresh";
}
return (deliver);
Any assistance is appreciated.
Thanks,
Travis
