Per page staleTimes configuration

[hubertoschusch]

Goals

I am using dynamic routes with prefetching on the server to improve load time, but I also want to cache the passed data on the client for example for 5 minutes. So not every new revisit to the page causes a server request, which causes the client to wait until the request is done (Like using tanstack query caching).
This is currently possible via the EXPERIMENTAL staleTimes configuration next.config.ts but only configurable globally. Now I might want to have a shorter caching time on one page than on another and that is currently not possible.

Background

I think this is a basic caching functionality and should NOT be experimental and also should be configurable per PAGE. I don't know how this is not a bigger issue for people?

Proposal

Make staleTimes configurable per Page just like the route segment config variables

TLDR

Caching dynamic route page response from nextjs server on client side (Router cache) currently only possible via EXPERIMENTAL and globally configured staleTimes variable.
