分 SSR 和 CSR 两种情况进行讨论。
when a page is CSR fallback, the CSR app is served with the Cache-Control:no-store header to ensure it is not cached by the caching layer.
when a page is CSR fallback, the CSR app is served with the Cache-Control:no-store header to ensure it is not cached by the caching layer.
On the other hand, if a page request is served in SSR mode, the response returned by SSR server could be cached in CDN. In this case, the response does not have Cache-Control: no-store in the header.
Cache-Control: no-store is only there in CSR fallback case.
