How can I prevent duplicate fetch

[WreewanMorhee]

I know shouldRevalidate this function
but let me describe my question first:

I go to first page: mydomain/l?page=1 (fetch data about page=1, we assume data here called A_Data)
and got to next page : mydomain/l?page=2 (fetch data about page=2, we assume data here called B_Data)
then
when I back to mydomain/l?page=1
How should I still using previous A_Data and prevent duplicate fetching about page=1 ?

You need to cache it, one way could be to use an HTTP cache with the Cache-Control header to cache the whole response, note that the document response and the data response will have separate caches in this case.

Another way is to use a server-side cache (e.g. lru-cache or Redis) to cache the data server-side, which will let you have more control and even share the cache between users if you want.
