Hello,

I’m trying to figure out what settings to configure for [Stale Page Caching](https://documentation.bloomreach.com/14/library/concepts/request-handling/hst-enterprise-caching.html) (SPC) and [First Level Page Caching](https://documentation.bloomreach.com/14/library/concepts/request-handling/hst-page-caching.html) (FLPC); I understand that to enable the former I first have to enable the latter.

My question is: do the two caches cache items in memory using the same or separate collections?

I’m guessing the answer is ‘separate’ but would prefer to confirm. I’m trying to estimate what numbers I should set the `maxEntriesLocalHeap` for SPC and `maxSize` for FLPC, and if they add up, I have to take this into account as it increases requirements for heap size.
