Meziantou.FrameworkNoCacheMiddleware Class
Ensures responses are marked as non-cacheable when no Cache-Control header is already set.
public sealed class NoCacheMiddlewareRemarks
Register this middleware after any component that serves cacheable content, such as UseStaticFiles: the static file middleware sets ETag and Last-Modified but no Cache-Control, so an earlier registration marks every static asset as non-cacheable.
Because the default includes no-store, responses defaulted by this middleware are not stored by UseResponseCaching, UseOutputCache or a CDN. Responses that set their own Cache-Control are never modified.
