Koala features response caching, internally spelled as "cash". This allows you to avoid using complex varnish and such infrastructure to cash dynamic pages. For example, you may want to cache pages for visitors, but not for users as user pages are all customized.
Response caching is internally opt-in as it requires a database store. See koa-cash for more details.
All options passed to koa-cash must be hashed
by .cash.
