This sample illustrates the usage of ASP.NET Core (xref:)Response Caching Middleware with ASP.NET Core 2.x. For the ASP.NET Core 1.x sample, see ASP.NET Core Response Caching Sample (ASP.NET Core 1.x).
The application sends a Hello World! message and the current time along with a Cache-Control header to configure caching behavior. The application also sends a Vary header to configure the cache to serve the response only if the Accept-Encoding header of subsequent requests matches that from the original request.
When running the sample, a response is served from cache when possible and stored for up to 10 seconds.
