Cache location for cached streaming mode?

I wondered what the location for the cache if you used the new(ish) cached streaming mode for https? I have a few problems with Qobuz disconnects, so using the cached option appeals, but I try to avoid lots of writes to my main ssd - the lms runs on a pi. So, I thought I could change the cache location in server.prefs to a locally mounted USB but wanted to check if the normal cache folder is used for the streaming cache.
