For the last 15 days there has been a sudden drop in the number of requests served by cloudflare. There has been no change in any cache rules. I have gone over the logs. Only thing that has happened is a cache purge. But we do this once every 2-3 weeks, so don’t know what is causing this.
Possibly any change on your server which changed the caching headers and now prevents Cloudflare from caching?
Whats the URL? Are your visitors from a very diverse set of locations or rather from the same area (regarding the cache purge and the likelihood of the datacentres simply needing the recreate the cache globally)?
See my headers below:
Your origin returns the following headers:
< Cache-Control: max-age=31536000, public
$ curl -svo /dev/null -k https://www.metro-online.pk/images/appicon.png --resolve www.metro-online.pk:443:220.127.116.11 2>&1 | grep '< ' < HTTP/1.1 200 OK < Date: Sat, 30 Nov 2019 13:18:01 GMT < Server: Apache < x-frame-options: DENY < X-XSS-Protection: 1;mode=block < X-Content-Type-Options: nosniff < X-Permitted-Cross-Domain-Policies: none < Last-Modified: Thu, 22 Nov 2018 10:49:18 GMT < Accept-Ranges: bytes < Content-Length: 7576 < Cache-Control: max-age=31536000, public < Expires: Sun, 29 Nov 2020 13:18:01 GMT < Strict-Transport-Security: max-age=31536000 < Set-Cookie: HttpOnly;Secure < Content-Security-Policy: frame-src https://secure.livechatinc.com/ https://metroonlinepk.firebaseapp.com/ https://metro-online-web.firebaseapp.com/ https://app.adfilius.com < Access-Control-Allow-Origin: * < Connection: close < Content-Type: image/png
Cache is bieng BYPASSED at the moment.
Any help would be great.
Try removing that “Set-Cookie” header. It is not valid anyhow and cookies can prevent Cloudflare from caching.
