Hi All,

I have played around with this most the day. I have seen a few other forum posts talking about how to enable static asset caching.

app.UseStaticFiles(new StaticFileOptions
            {
                OnPrepareResponse = ctx =>
                {
                    const int durationInSeconds = 60 * 60 * 24;
                    ctx.Context.Response.Headers[HeaderNames.CacheControl] =
                        "public,max-age=" + durationInSeconds;
                }
            });

I have tried everything and it just does not seem to be cachign whatever I do or wherever I put the app.UseStaticFiles

Has anyone got this working? And can you send me a copy of your startup.cs file so I can compare this with mine.

As you can see in the screenshot the images are just not flagging up as cached.
