Will Flask-Caching have FileSystemCache client-side caching?

Question

caching

There is a code

cache = Cache(app, config={
    'CACHE_TYPE': 'filesystem',
    'CACHE_DIR': r'C:\сache_directory_BullsAndCows',
    'CACHE_DEFAULT_TIMEOUT': 86400,
})

And it stores the cache, as specified, in CACHE_DIR. Maybe it's a stupid question, does it keep the cache as on the client side, or does it treat my file system as the server's file system? If the correct answer is the second, then how can Flask implement client-side caching?
