public <K,V> RequestCache<K,V> createRequestCache(String name)
The cache will behave identically to one created by
except that calls to
get without a supplier will throw an exception
for values that are not already in the cache. This is mainly intended for cases where only the

cacheLoader- the loader that provides cached values
