Im trying to figure out some ways to extend the response headers with some info
of the request. What I want for now is if it was a hit or miss and which
backend it used.
I cant figure out how to know which backend it used. The only way i know of is
if the backend would deliver a header with host name or something similar. Is
there any way to do this in VCL?
I thought I could do like this to see if it was a miss or not but it didnt
work. Im not even sure if the Age-header is always 0 on misses or if it could
be 0 on hits too?
sub vcl_deliver {
if(resp.http.Age > 0) {
set resp.http.X-Cache = "HIT";
} else {
set resp.http.X-Cache = "MISS";
}
}
