Can I nest cache functions

Can I nest cache functions and does it prevent multiple calls to the db, for instance 
export const getAuthCache = cache(async () => {
  'use server'

  return getAuth()
}, 'getAuthCache')

export const requireAuthCache = cache(async () => {
  'use server'

  const auth = await getAuthCache()
  if (!auth?.user) {
    throw redirect('/auth/signin?error=unauthorized')
  }
  return auth
}, 'requireAuthCache')

export const getAccountCache = cache(async () => {
  'use server'
  const auth = await requireAuthCache()
  return getAccountById(auth.session.selectedAccountId)
}, 'getAccountCache')
export const getAuthCache = cache(async () => {
  'use server'

  return getAuth()
}, 'getAuthCache')

export const requireAuthCache = cache(async () => {
  'use server'

  const auth = await getAuthCache()
  if (!auth?.user) {
    throw redirect('/auth/signin?error=unauthorized')
  }
  return auth
}, 'requireAuthCache')

export const getAccountCache = cache(async () => {
  'use server'
  const auth = await requireAuthCache()
  return getAccountById(auth.session.selectedAccountId)
}, 'getAccountCache')
do i get the benefits of cache from the above code?

I don't think nested cache functions work well. You can refactor it out

so cache is only useful when called from the frontend? What is a good way to refactor the above, auth function in particular which needs to be called in almost every server function

Just use getAuth as a normal function without cache wrapper cache wrapper mainly only used with createAsync or preload

Just skimmed through the cache source code and there is a bunch of isServer logic. I would imagine from this that nested cache calls should work fine. Unless im missing something here https://github.com/solidjs/solid-router/blob/main/src/data/cache.ts

I think it works unless you like redirect or something
