if you share the state on server, the state will share along with different user.
with server component, we could fetch the data we need in the component

Yeah i know but if i want to validate the users session in three components, i wonder if there is a good way to not have to do the same call in all of them.

from lucia doc

If i cache a validateSessionToken in my layout and then export it to it's children. Then all children will get the same result and the session wont bleed to other user, if i'm understanding this correctly?

yes the result from react cache only live in a single request

Or should i cache it where i define the method, I don't really understand how this works. Will it work the same if if i cache the original method?

Oh perfcet

seems like what i want

when the request is done, the result is clear

Should i cache the original function or create a copy?

what do you mean?

should i

const cachedValidation = cache(validateLogin);

or

const validateLogin = cache(async() => {
  return login()
})

const cachedFetchUsers = cache(fetchUsers)

both are fine, but I prefer this

so I know that function is a react cache version

Ok, thank you!
