分 s-s-r 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 s-s-r mode, the response returned by s-s-r 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.
