z2300520z 你走了 cdn ,按理不应该卡。cf 的规则默认不缓存 html ,估计流量都打到你源站
刚才看了一下,你的 html 和图片的响应 cf-cache-status 都是 BYPASS ,这是没缓存啊
https://developers.cloudflare.com/cache/concepts/cache-responses/BYPASS
The origin server instructed Cloudflare to bypass cache via a Cache-Control header set to no-cache, private, or max-age=0 even though Cloudflare originally preferred to cache the asset. BYPASS is returned when enabling Origin Cache-Control. Cloudflare also sets BYPASS when your origin web server sends cookies in the response header. If the Request to your origin includes an Authorization header, in some cases the response will also be BYPASS. Refer to Conditions in the Origin Cache-Control behavior section for more details.
