+When playing around with caching, because I don't want to be a burden to the official backend, I was trying to understand
+how I could utilize [workers caching API](https://developers.cloudflare.com/workers/runtime-apis/cache/) in that effort.
+
+The response from the official backend has a `Cache-Control` header set to `private`, meaning that clients should decide
+themselves how to cache results. Browsers will generally not cache results with that header key value, CloudFlare adopted
+the same behavior.
