Setting the 'Content-Disposition' header for arbitrary content

[ee-usgs]

I am streaming CSV data from a Controller method - How do I set the Content-Disposition: attachment header so that browsers download it instead of display it?

I see that for sending 'Files', this is done automatically, but I don't intend to use either of the two return types shown in that example, my method signature looks like this:

@Get("/result{?values*}")
public Flux<String> result(@Nullable @QueryValue("values") Map<String, String> filterMap);

Isn't there a way to just annotate the content disposition? It seems weird to me that it currently seems tied to specific response types - In general, any response of any type might be inline or attachment. It's an independent concern.

Thank you in advance for the help.

You can set the header manually by returning a HttpResponse.

@yawkat If I return a HttpResponse, I break all of Micronaut's automatic handling of Flux.
