How to set Cache-Headers via Middleware before Mvc and not be overriden by ResponseCacheAttribute?

I have an ASP.NET Core 2.2 (preview3) project with several controllers decorated with ResponseCacheAttribute like this one:
[ResponseCache(Location = ResponseCacheLocation.Any, Duration = 60)]
Now I want to add a Middleware which is supposed to run before MVC and before Caching which might determine to not allow any clientside/proxy caching for this response.
But if I set context.Response.Headers[HeaderNames.CacheControl] = "no-cache, no-store"; in the Middleware it gets overwritten by the ResponseCacheAttribute of the controllers later in the pipeline.
So my pipeline looks like this:
- Use new Middleware: checks for cachability, sets
no-storeunder specific conditions - UseResponseCaching
- UseMvc
How can I get this to work?

Have you tried writing the header after the call toawait next()in your middleware?

Thanks. I tried that. But Response has started and can't be modified at this state according to the Docs (docs.microsoft.com/en-us/aspnet/core/fundamentals/middleware), it throws an exception.

Right, hmm.. There might be some feature in the HttpContext's Features collection that allows you to disable the MVC caching feature.. Not sure though

Yes, there is theIResponseCachingFeature, but then I have to register my middleware after ResponseCaching, otherwise it's not present. And I can't find any API to remove a feature...
