I am troubleshooting webiste loading performance issue. We observed the website loaded almost instantly under incognito (Chrome) or private mode (Firefox) but took 7-10 sec under normal mode.
Further investigation found cf-cache-status returned “DYNAMIC” under normal mode but it shows “HIT” under incognito and private mode with same URL.
According to CloudFlare document, DYNAMIC means not cached and requests will always go to the origin that may explaining the issue.
However, why cf-cache-status return different status between normal and private/incognito mode with identical URL? How do I resolve the problem?
Much appreciate your support!
