Link to the code that reproduces this issue

https://stackblitz.com/github/Fredkiss3/next-dynamic-test-updated?file=app%2Flayout.tsx

To Reproduce

1. Click on the link above
2. Go to /dynamic (either by clicking on the link or by clicking on the button)
3. You will see on the console the current time
4. Try navigating to another page, then navigate again to /dynamic, this time you won't see anything printed on the console
5. If you wait 30+ seconds, and navigate again to /dynamic you will see the current time logged in the terminal

Describe the Bug

There were some improvements about route segment caching on client navigations introduced by this PR #48383 , but with that now <Link prefetch={false}> is not respected anymore even though it is said that a link without prefetching should not be cached at all and always refetched between navigations, this is a bug because there are some cases where we want always fresh data like auth gated routes with JWT sessions limited in time, and more.

Expected Behavior

When using a Link with prefetch={false} the page should not be cached at all and all subsequent navigations should refetch and call the server.

Closing as it is how it's supposed to work.

Closing as it how it is supposed to work.

@Fredkiss3 can you elaborate here? It is desired, expected behavior that Links using prefetch={false} will see caching behavior? I guess this is the same caching behavior as a normal Link?

Also, where did you get this information?

[Fredkiss3]

• Yes, prefetch={false} disable prefetching, but not caching
• I asked a core member of the team who worked on the PR (feedthejim) and he confirmed that
• I would have preferred for it to not also cache, but it is how it's supposed to work

For pages that do not need caching, it seems like there will be a way to specify for how long a page should be cached on the client, It is said in the PR :

Follow ups

• we may add another API to control the cache TTL at the page level
