Hello!
I have problem how to debugs current response time to upstream, my
configuration is looks likes :
....
upstream upstream_distribution {
server full-fqdn.tld;
}
# common configuration
location ~ \.(jpe?g|png|gif|webp)$ {
proxy_pass http://upstream_distribution;
proxy_cache_use_stale error timeout updating http_500
http_502 http_503 http_504;
proxy_cache_valid 200 302 301 3d;
proxy_cache images;
proxy_cache_valid any 3s;
proxy_cache_lock on;
proxy_cache_min_uses 1;
proxy_ignore_headers Cache-Control Expires;
proxy_hide_header X-Cache;
proxy_hide_header Via;
proxy_hide_header ETag;
more_set_headers "X-Cache: $upstream_cache_status";
more_set_headers "X-RTT: $upstream_response_time ms";
}
# common configuration
....
The problem is, the request was cached by nginx and didn't send
response to upstream, so the response of the header was :
age:94
cache-control:max-age=604800, public
content-length:143862
content-type:image/webp
date:Fri, 04 Nov 2016 09:03:44 GMT
last-modified:Fri, 04 Nov 2016 05:41:55 GMT
x-rtt:ms
server:nginx
status:200
x-cache:HIT
Is it possible to capture upstream_response_time while the content was
cached?
Any hints and helps are appreciated.
